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.

∙ 11y agoA Class B push pull amplifier is a type of push pull amplifier where when one side is pushing (or puling) the other is in cutoff. This significantly reduces power consumption and increases efficiency. However it adds crossover distortion as the twos sides go in and out of cutoff. A Class AB push pull amplifier eliminates this crossover distortion at a small loss of efficiency.

Which amplifier has more efficiency than class b amplifier?
Class C amplifier.. A class D amplifier is more efficient than class B, and is more efficient than class C as well.
What are the system applications of a class B amplifier?
Class B operated amplifier is used extensively for audio amplifiers that require high power outputs. Its also used as the driver and power amplifier stages of transmitters.
A class B amplifier is biased?
hi i m nishikantanswer is: in class B devices are biased approx at cutoff.
RF amplifier of an AM receiver is normally biased in class a class b class c?
class C because Class C also provides better signal,rejects unwanted signal.class c
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.
Why the name pushpull is given to pushpull amplifier?
Because first one side of the amplifier pushes on one half cycle then the other side of the amplifier pulls on the other half of the cycle.
Which amplifier has more efficiency than class b amplifier?
Class C amplifier.. A class D amplifier is more efficient than class B, and is more efficient than class C as well.
What are the least efficient of class of amplifier?
class b amplifiers as for class b amplifier the 'Q' point is near to cut of region.
What is a advantage of class B amplifier?
class b amplifier is in between of a and c.so dont warry abt ds
What is the efficiency of class b linear RF AM amplifier?
the approximate efficiency of a class b linear RF AM amplifier is 35%
What is the main difference between a class 'A' and a class 'B' amplifier?
A class "A" amplifier amplifies the entire waveform, a class "B" amplifier only amplifies the first 1/2 of the wave form. See the images in the related link.
What are the system applications of a class B amplifier?
Class B operated amplifier is used extensively for audio amplifiers that require high power outputs. Its also used as the driver and power amplifier stages of transmitters.

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.
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)
