What is meant by doping?
Doping: Semiconductors in its extremely pure form are termed as intrinsic semiconductor such intrinsic semiconductor to which several suitable impurities is added in extremely small amount are termed as extrinsic semiconductor. That process is termed as doping and impurities are as termed as doping agent. Generally the doping agents are pentavalent atom as arsenic, antimony or trivalent atom as indium, gallium and aluminium.
Q. Explain crossbar exchange, with all call processing steps and diagrams. Ans: The basic concept of crossbar switching is to provide a matrix of n x m sets of contacts with
Q. What are transistor amplifiers? What is meant by efficiency of an amplifier? What is amplifier coupling? The AMPLIFIER is a device that enables an input signal to control an
(a) Evaluate whether the sinusoidal signal x(t) = A cos (2πf 0 t + θ) is an energy-type or a power-type signal. (b) Show that any periodic signal is not typically energy type, a
Since a controlled source acts at its terminals in the same manner as does an independent source, source conversion and application of KCL and KVL relations are treated identically
Q. Explain Multiplexing Systems? A multiplexing system is one in which two or more signals are transmitted jointly over the same transmission channel. There are two commonly us
The creation of a magnetic field in a ring may need to be accessed by means of an air gap. This is typically used to apply the magnetic field to a current carrying conductor to pro
A voltage amplifier without feedback has a nominal gain of 500. The gain, however, varies in the range of 475 to 525 due to parameter variations. In order to reduce the per-unit ch
Q. Important function of common control subsystem? If a call is destined to a number in an exchange other than present one processing the digits, initial translator generates t
a) What is meant by frequency response and how would you check the performance of your amplifier? b) Calculate the Voltage Gain of your amplifier at a range of frequencies suffic
