What is Class B push-pull amplifier?
When we get amplifier output current for 180 degrees of input. then it's called B class amplifier. In a push pull class B amplifier one of the two power transistors or other amplifying elements handles the positive half of the waveform and the other element handles the negative half of the waveform. In practice, push pull audio amplifiers are usually class AB; each power transistor handles slightly more than 180 degrees of input. This minimizes distortion (crossover distortion) when one of the two transistors ceases output and the other takes over.
What are the advantages of push pull amplifier?
The advantage of this circuit is that there is very little current taken if there is no signal input
What are the uses of complementary symmetry class B push-pull amplifier?
Sound amplification. Servo control systems.
Why even harmonics are not present in push pull amplifier?
Symmetrical push/pull circuits must cancel even ordered harmonics, like f2, f4, f6 and therefore promote odd ordered harmonics, like (f1), f3, f5 when driven into the nonlinear range.

Applications of push pull class B amplifier?
nthing
Is pull push amplifier is known as class b amplifier?
No, a push-pull amplifier can be built class A, class AB, class B, or class C depending on application.class A push-pull is used for low power audio usuallyclass AB push-pull is used for high power audio usuallyclass B and class C push-pull is used for very high power radio usually (B is typical for AM and C is typical for FM)
Is odd harmonics present in push pull amplifier?
Odd harmonics are theoretically the only harmonics that are produced by a push-pull amplifier, and even the level of odd harmonics should be very low.
Is push-pull amplifier is known as class-B amplifier?
Yes... Obviously.. Since technology is getting advance and you can even search it on wikipedia...

What would be the purpose of a headphone amplifier?
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
What are the uses of complementary symmetry class B push-pull amplifier?
Sound amplification. Servo control systems.
Why the name push pull is given to class B power amplifier?
Because two amplifiers are used to accomplish class B power amplifier. One is used to push the current and the other one is used to pull the current. These two amplifiers are almost same but one is connector supplied and the other one is emitter supplied.
What advantage does the class B amplifier have over the class A amplifier?
The main advantage is lower power dissipation as the amplifier is not conducting half the time, however the resulting disadvantage is that it is nonlinear unless the more complex push-pull amplifier design is used (requiring about twice as many components).
