What is the need of filter in rectifier circuits? all i know is that rectifier converts ac sine wave into pulsating dc. to overcome this we use filter. Please explain this further in detail with diagrams if possible.

Sorry Moderator. But this isn't a homework. My lecturer gave a lecture on this topic today. So i wanted to know more about this, Hence i asked this here

What is oscillator ? How it is useful ? What are its application in Electrical and Electronic Circuit/System

Very well explained. Thanks Enthalpy for your detailed explanation. This will help me a lot in my studies

You interpreted it wrong. I meant to say what's the efficiency of Class B Amplifier? For this you'll have to explain me its waveform and calculate the efficiency with and without distortion.

I don't understand.

How to find overall efficiency of Class B Amplifier ?

What is class B amplifier and where it is used ?

Glad you helped me. I know about a distortion now. Does distortion occur in every output or is there any specific conditions for that

It really helped to after drawing sketch. What are the components Harmonic Distortion brings in a pure wave form what's it's time period to last. ?

V inst =V maxsin (wt+p) , i understand this but we haven't come across Fourier or Harmonic Analysis yet. If say in simple word, "as soon as the amplitude of sine wave increases gradually, then there is a gradual drop in the amplification." Is this term logical and correct. If the sine wave is no longer a true sine wave of input, then the distorted wave is know by what name. Or its simply known as Distorted Output. What if we connect a filter in the output of any signal to decrease distortion somewhat or a rectifier.

My lecturer said, transistor is a non linear device. And Power amplifier handle large signal hence there is always distortion. Due to distortion the output power targeted on the basis of non distortion is not correct. But i didn't agree with him. How can amplifying large signal be only reason?

Yeah i would like to know more like what is crossover distortion and others. And yeah is there any electronic circuit which can overcome all the distortion all in one.

Thanks. By the way this isn't a homework. My lecturer gave a us a lecture on Power Amplifiers, so i wanted to know more, you know "curiosity"

What other type of distortion's are present ?
