Q1:

Crossover distortion behaviour is characteristic of

A class A O/P stage

B class B O/P stage

C class AB output stage

D common pulse O/P state

ANS:B - class B O/P stage

It is a characteristics of class B output stage as the amplifier is biased in cut-off region. In class B amplifier, two transistor are operated in such a way that one is amplify the half cycle and second is amplify -ve half cycle.
