Q. What is an amplifier? What are the various types of amplifiers?
AMPLIFIER: A circuit that increases the amplitude of the given input signal is an amplifier. A small a.c. signal fed to the amplifier is obtained as a larger a.c. signal of the same frequency at the output. They constitute the essential parts of many communication circuits such as television and radio.
Consider the circuit shown in Figure (a) in which the switch S has been in position 1 for a long time. Let the switch be changed instantaneously to position 2 at t = 0. Obtain v(t)
