Classification of Communication: There are two basic classification of communication systems, baseband systems and passband systems. In baseband systems, the signal is transmitted without modifying the frequency content. A simple…
Recursive and Non Recursive Realisation: In recursive realisations, the present output value depends on the input (past and present values), as well as the previous value of the output. It…
Pole Zero Plot: Pole Zero Plot - The variable s is a complex variable. Hence a complex plane is required to indicate the values of s graphically. A complex plane…
Multiplexing in Electronic Communication: Multiplexing in Electronic Communication is the sending of a number of separate signals together, over the same cable or bearer, simultaneously and without interference. There are…
Gunn Diode Working Principle: A practical Gunn Diode Working Principle consists of a slice like the one shown in Figure 12-24, sometimes with a buffer layer between the active layer…
Gunn Effect: In 1963, Gunn discovered the transferred electron effect which now bears his name. This Gunn Effect is instrumental in the generation of microwave oscillations in bulk semiconÂductor materials.…
Wave Analyzer Articles: What is Wave Analyzer? It can be shown mathematically that any complex waveform is made up of a fundamental and its harmonics. It is often desired to measure…
Root Locus Plot: In the electrical drives employing closed loop control techniques, it is often necessary to investigate the effects of changing the parameters of the system on its stability.…
