A complimentary-symmetry amplifier is a power output stage using two transistors. One is an NPN and the other is PNP, and normally the designer will use transistors that are compliments of one another (TIP31C for NPN and TIP32C for PNP, for example).
The transistors are hooked in series in a sort of push-pull arrangement. The NPN's collector connects to the positive voltage rail and the PNP's collector connects to either A) ground or B) a negative but equal voltage rail. The emitters are connected together and are at either A) 1/2 the positive voltage supply or B) zero volts. In A) a large coupling capacitor must be used to connect to the speaker while in B) there is no DC difference and the speaker can be directly connected.
This configuration is similar to a "self-inverting push-pull" circuit in tube-speak. A positive-going input pulse will cause the NPN to conduct more and the PNP to conduct less. A negative-going pulse will cause the PNP to conduct more and the NPN less. It's useful for a small, transformerless output stage but there are more efficient and clearer designs. I can't tell you much more as I'm just now getting into transistors and am still experimenting with this circuit.
That was probably more info than you were wanting, however. Good luck.

What are the uses of complementary symmetry class B push-pull amplifier?
Sound amplification. Servo control systems.
Why you use pushpull complementary symmetry for class B power amplifier?
Because the output device in a class B amplifier are biased at cutoff, they only amplify one half of the input waveform, so a complementary stage, biased at class B, is needed to output the other half. There are several circuit layouts to do this.
What are the uses of complementary symmetry class B push pull amplifier?
Class b complementry symetry is nothing but the amplifier which have double amplification,in this the transistor used is npn and pnp so one get the phase shift of 180 and other also so the total phase shift is 360 degre.so it is very useful for the amplification purpose
What is wideband amplifier?
A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave. The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ). The "opposite" concept is the narrow-band or tuned amplifier. There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor. end-
What is complementary symmetry power amplifier?
A full and true "quasi complementary symmetry power amplifier" is an audio amplifier whose power output section is typically comprised of 2 of the same NPN output transistors, (generally matched) and 2 of the same PNP or NPN driver transistors, (also generally matched). Driven by dual matching + & - DC voltage power supply voltages. With the exception of the bias control circuit components, each half of the output circuit are exact mirror images of one another. Each half of the circuit amplifies the positive and negative half cycle of the audio signal. The theory is, "it is much more likely to perfectly match the performance of each half cycle of the amplifier by using this circuit design criteria. Only the most esoteric amplifier manufactures used this design in the late 60's and 70's.
