[hdrzaman]

it is an amplifier that amplify the signal in two portions. one portion of the circuit is active for half cycle and other for the next half.

 

[quaternion]

It is an amplifier whose amplifying device(transistor) conducts half the time of the input signal cycle (considering a sinusoidal component of the input wave).It is usually designed by two complementary transistors (either npn and pnp or 2 npn also may be implemented by MOS) making pushpull action which hdrzaman take about.

Check IanP's good advice and link. After studying that go here:

[bas]

it is the push pull power amplifier
2 transistor are used with or without a transformer
