    Hi,

    What distiguishes an class A amplifier from a class B amplifier?I know that in class A amplifiers transistors conduct during the entire cycle of signal and in a class b they conduct for half the cycle sinal.Moreover the position of the resting point is different.
    In class B amplifiers there still is a possibility of crossover distortion.
    Besides these aspects (period of conduction of the input signal, resting point) are there any other aspects que distinguish these two types of amplifiers

    Thanks

    But the more important aspects are those i have mentioned rigth?(period of conduction of the input signal, resting point and crossover distortion in class B amplifiers)

    Thanks

    " . . . in class A amplifiers transistors conduct during the entire cycle of signal and in a class b they conduct for half the cycle sinal . . ."


    Fundamentally, Yes.

    Class A -> High fidelity reproduction
    Class B -> Sheit reproduction
