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.

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.
Why Amplifier of class B has high theoretical efficiency of 78.5 percent?
The Class B amplifier is a push pull amplifier with 78.5% efficiency. The high efficiency is due to the absence of power consumption during idle time which simultaneously increases the efficiency.
How is transformer saturation avoided in class B push pull amplifier operation?
In class B amplifier no DC biasing required, thus lack of of DC current in inpunt and load, saturation of core avoided
Is force a push or pull?
A force can be either a push or a pull.
What is A or C biasing?
The three standard forms of analog amplifier biasing are:class A - the amplifier is biased in the center of its linear operating range, this is the most linear but least efficient type of amplifier (because the transistors or tubes are always conducting, even when there is no signal to ampliify).class B - the amplifier is biased at the cutoff point, this is an efficient amplifier but is only linear if operated as a push-pull amplifier (because the transistors or tubes are in cutoff and not conducting when there is no signal and through one half of every cycle, a class B push-pull amplifier has two sections that operate on alternate halves of the cycle).class C - the amplifier is biased in hard cutoff so that only the peaks of the input signal are amplified, this is the most efficient amplifier (because the transistors or tubes may be in cutoff and not conducting for more the 85% of the time) but it is not capable of linear amplification. An amplifier biased as class C is only suitable for use in RF transmitter power stages, where a resonant LC tank circuit will be excited into oscillation by the output of the amplifier and complete the missing parts of the cycle.There are other forms of biasing (e.g. class AB) analog amplifiers that get some of the advantages of two of the standard forms. There are also forms of amplifiers having other nonstandard classes (e.g. class D) that are not analog amplifiers, but instead operate by amplifying pulses.
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.

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)
What is the purpose of diodes in a push pull amplifier?
To bias the transistors at 0.7 Volts.
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 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 uses of class b push pull amplifier?
Sound amplification. Servo control systems.
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 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).
