What is a advantage of class B amplifier?
class b amplifier is in between of a and c.so dont warry abt ds
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 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.
A class B amplifier is biased?
hi i m nishikantanswer is: in class B devices are biased approx at cutoff.
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)
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
What are the basic types of amplifiers?
based on i/p:a) small signal amplifier b) large signal amplifierbased on o/p:a) voltage amplifier b) power amplifier c) current ampbased on bandwidth:a)untuned amp(wideband) b)tuned amp(narrowband)based on biasing condition:a)class A amp b) class B amp ......e)class D amp f) class s ampbased on no. of stages:a)multistage amp b) single stage amp
