Experiment is defined as: 1. Scientific test: a test, esp ecially a scientific one, carried out in order to discover whether a theory is correct or what the result of a particular course of action would be. 2. Doing something new: an attempt to do something new or to see what would happen. So, what we have here is a Handbook o f Laborato ry Experiments. This Handbook is prepared after extensive simulations of the cir cuit with some electronic and engineering software such as Multisi m, PSpice, Circuit Logi c and MA TLAB. The Handboo k is des igned basically to assist both tutors and students in the conduct of laboratory experiments. It The Oxford Dictionary defines: 1.http://karate.infotip.cz/userfiles/defence-capability-development-manual-2006.xml Handbook as a book that Handbook contains inf ormation a nd instructions about the operation of a m achine or how to do something. 2. Laborat ory (informally, Lab) as a facility that provides a controlled condition in which scientific or technological research, experiments or measurement may be performed. Experiment is defined as: 1. Scientific t est: a test, especially a scient ific one, carried out in order to discover whether a theory is correct or what the result of a particular course of action would be. 2. Doing something new: an attempt to do something new or to see what would happen. The texts have been written in a simple technical language a nd the mathematics behind the experiments clearly derived and expl ained. This book has added to the wealth of knowledge, especially in physics, Electrical and Electronic and Communications engineering for st udents in T ertiary institutions, such as Polytechnics, Monotechnics and Universities. This Handbook contains five sections and a total of thirty- three experime nts, which can be categorized into B asic Electronics Software, Communication System Engineering experiments and Optical Communication experiments. Each experiment contains details of objectives, materials, the oretical background and procedures. The procedure involves steps and questions in understanding the experiment being conducted. We wish to seize this opportunity to express our profound gra titude to all those that ha d made the preparation, conduction of the experiment and publication of this hand book a reality. Palapye, Bo tswana 2017 ????? ? ??????? Laboratory course enables students to do experiments on t he fun damental l aws and principles encoun tered in t he theoretical work. In these formative years, the student is made to learn the basic electronics and engineering software, relevant to electrical engineering, and ge t familiar with the basic hardware with special attention to spectrum and network analyzers.http://eco-region31.ru/boss-dr-660-manual-0 Students are also made to lea rn and a ppreciate the design of filter circuits, oscillators, phase- locked loops, signal modulators and de-modulators and fibre-optic communications. Other aspects of Electrical and Elec tronic practical experiments were all subs tantially considered. It is aimed at ensuring tha t the students become suffic iently familiar with the theoretical aspects of the experiments and consequently sharpen their focus on the expected results. The laboratory ex ercises in this manual are designed t o provide a practical knowledge of som e of the more fundamental pri nciples of Electrical, Computer and T elecommunications Engin eering. All the experiments i n this hand book were s imulated and t ested in a laboratory to record the res ponse of each circuit, and they were all found to be working properly a s expected. While working through the manual, the student will become more fam iliar with the manual a nd the basic software, hardware and communication circuits in Electrical and Electronic Engineering. In order to fully understand the principle being investigated, the student is a dvised to read extensively, the rela ted topics, before enteri ng the laboratory. At the end of each laboratory session, questions and exercises should be completed and ret urned to the Examiner for proper grading as scheduled. It should be understood that any use of electricity inherently involves some degree of safety hazard. The best way to achieve safety in the us e of electrical equipment is to adhere t o all of the safety rules, which include: 1. Understanding the function ing of the equipment you are proposing to use and its rating 2. Understanding the application to which the equipment is to be used for 3.

A mplitude modulators are generally of two types: low level and high le vel. In low-level modulation, the AM is g enerated a t an early ampl ifier stage, and in high-level modulation, the final amplifier stage of a transmitter is modulated. The choic e between low-level a nd high-level modulat ion is made on the basis o f the transmitter power output. High-level modulation i s the choice for high-power t ransmitters, which use Class-C amplifiers because they have a higher efficiency in high-power applications. Class-C ampli fiers would distort the modula ted carrier, if the modulation occurred in an early stage of the ampli fier. However, high-level modulation requires the modulating signal to be amplified to a higher power t han with low-level modulation. L ow-level modulation is the ch oice for low-power transmitters because they do not require high-efficiency Class-C amplifiers to a mplify the modul ated carrier. The low- level m odulation does not require much amplifica tion of the modulating s ignal; i t is more econ omical for low-power applications than high-level modulati on. This makes the bandwidth wider t han the allocated bandwidth, causing interference with other signals. This overmodulation interference is called sideband splatter. An amplifier circuit that will a ccomplish this is shown in Fig. 19.0. It cons ists of an operational amplifier (741) and an n-channel JFET (MPF10 2) us ed as a variable resistor. The op-amp is connected as a non-inverting amplifier with a carrier sine wave generator applied to the amplifier input. The gain of the amplifier ( A ) is 1 F i R A R (19.1) Where R i is the drain-source resistance of the n- channel JFET. The negative voltage s ource places a reverse bias on the JFET gate-source junction. The modulating signal is applied to the gate of the JFET through capacitor C and Causes the r esistance ( R i ) of the JFET t o vary according to the modulating signal. This will cause t he gain of the amplifier to be a function of 1 in addition to the modulating signal instantaneous amplitude. V oltage gain block K is used t o adjust the modulating s ignal voltage level ( V m ) to a value that will produce appro ximately 100 modulation when V m is equal to V C. Bec ause the amplifier i s not linear, some ha rmonics will be generated due to distortion. This will cause some additional side frequencies to be generated. Another w ay to amplitude modulate a carrier is to apply the sum of the carrier and the modulating signal to a nonlinear component or circuit that will produce an output as a function of the square of the input. A diode (or transisto r) will accomplish this objective. A diode (or transistor bas e-emitter junction) has a current ( I ) that is approximately equal to 2 I aV bV (19.2) Where V is the voltages across the diode (or transistor base- emitter), whil e a, b are constants. The resu lting output w ill be the carrier frequency and it s harmonics, the modulating signal frequencies and their harmonics, an upper carrier sideband and a lower sideband. A parallel band-pass filter tuned to the carrier, with a bandwidth wide enough to pass the carrier and sidebands, w ill filter out the remaining The s imple diode modulator is shown in Fig. 19.1 and will be used to demonstrate this theory. It consists of a resistive mixing network, a diode, and a parallel band-p ass filter. The carrier is applied to one input resistor and the modulating signal is applied to the oth er. This resistive network causes the t wo signals to be added. The added signals are appli ed to the nonlinear diode, which will produce the frequencies discussed previously. The band-pass filter is tuned t o the carrier frequency. It will filter out the harmonics and pass the carrier and sidebands, producing an amplitude-modulated carrier. Because the band-pass f ilter is not a perfect filter, additional harmonics may be passed at a reduced level, but it would produce s ome additional side frequencies, causing some distortion of the modulated carrier. A transistor in place of the diode, with the parallel resonant circuit in the collector circuit, would prod uce an amplifier AM carrier. At the receiver, the modulated carrier is amplified and demodulated to extract the original ba seband signal. A circuit that extrac ts the original baseband signal from t he modula ted carrier is called a demodulator or detector. T he AM dem odulator is the key circuit in an A M radio receiver. The simplest and most widely us ed AM demodulator is the AM diode detector, shown in Fig. 19.2. The diode detector is a half-wave rectifier circuit with a low-pass filter. The diode conducts during the positive half-cycle, the diode i s reverse biased and n o current flows through it or resistor R. This causes the voltage acr oss resistor R to be a series of positive pu lses, whose amplitude follows the am plitude of the modulated carrier. Capacitor C forms an RC filter with resistor R. The operation of the RC filter can be analyzed in the time domain or the frequency domain. First, we will analyze the filter in the time domain. Capacitor C charges quickly to t he peak value of a positive pulse th rough the low-r esistance forward-biased diode. When the positive pulse voltage drops to zero, the diode becomes reverse biased and the capacitor discharges slowly through resistor R. If the RC time constant is longer in comparison to the time period of one cycle o f the carrier, the capacitor will discharges only slightly during the time when the di ode does not conduct. When the next peak voltage occurs, the cap acitor will again charge quic kly to For this reason, the diode detector is sometimes referred to as an envelope detecto r. If the capacita nce of cap acitor C is t oo high, causing a long RC t ime constant, t he cap acitor discharge w ill be too slow for the ou tput volta ge to follow the change i n the modulating signal. This will cause a distor tion called diagonal distortion. If the capacitance of capacitor C is too low, causing a short RC time c onstant, the capacitor will discharge too fast and cause a large output ripple. If there is a large difference between the carrier frequency and the f requency of the modulating signal and the correct value for capacitor C i s selected, the out put waveform will be a close approxima tion to the original modulating signa l. If we exa mine the o peration o f the RC filter in the frequen cy do main, it can be considered a low-pass filter. This low-pass filter should pass the modulating signal frequencies and reject the carrier frequency and all other harmonic f requencies generated by the nonlinear di ode. If the correct value of C is selected for a cutoff frequency that is above the modulating frequencies a nd below the carrier frequency, the waveform across capacitor C will be a close approximation to the original modulating s ignal. If the cutoff frequency is too close to the carrier frequency, the output ripple will be too large. If the cutoff frequency is lower than modulating frequency, diagonal distortion will result. The cutoff frequenc y ( f C ) of the low-pa ss filter can be calculated fr om 1 2 C f RC (19.3) The purpose of coupling ca pacitor C C in the AM diode detector is to remove the dc component from the recovered signal. The coupling capacitor will elim inate this dc component because a capacitor can pass an ac signal but does not pass a dc voltage. The coupling capacitor ( C C ) and load resist or ( R L ) combination acts like a high-p ass filter. The modulating signal will be undistorted. The high- pass filter cutoff frequency can be calculated from the previous equation used for the low-pass filter. The cir cuit in F ig. 19.3 will demonstrate how an ac s ine wave applied to the input o f an AM modulator is reproduced at the output of a diode These communities are able to effectively coordinate themselves to achieve global objectives despite a lack of centralized planning, and the behaviour is referred to as swarm intelligence. Three types of insects are used for discussion: ants, termites, and bees. In addition, a study of the social foraging behavior of spider monkeys is presented. The performances of these swarm-intelligence-based algorithms were tested on common routing scenarios. The results were compared with other routing algorithms with varying network density and showed that swarm-intelligence-based routing techniques improved on network energy consumption with a control over best-effort service. The results were strengthened with a model of termite-hill routing algorithm for WSN.
