Q. Explain the classification of amplifiers on the biasing conditions?

Based on the amount of transistor bias and amplitude of the input signal, amplifiers can be classified as class A , class B, class     B and class c.

CLASS A AMPLIFIER: In a class A amplifier, the transistor is biased such that the output current flows, i.e. the transistor is on for the full cycle (360) of the input a.c. signal.

CLASS B AMPLIFIER: In the class B amplifier the transistor bias and the amplitude of the input signal are selected such that the output current flows ,i.e. the transistor is ON for less than one half cycle (180) of the input a.c. signal .

CLASS C AMPLIFIER: In a class c amplifier the transistor bias and the amplitude of the input signal are selected such that the output current flows i.e. the transistor is ON for less than one half cycle (180) of the input a.c. signal.
