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.
A class B amplifier is biased?
hi i m nishikantanswer is: in class B devices are biased approx at cutoff.
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.
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?

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 are the applications of Class B Power Amplifier?
Its used in collector amplitude modulation,Radio frequency recievers ..etc
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.
A class B amplifier is biased?
hi i m nishikantanswer is: in class B devices are biased approx at cutoff.
Amplifiers following the modulated stage in a low level modulation am system be?
linear circuits (class B push pull power amplifier)
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)
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.
