1. What is the use of feedback amplifiers instead of conventional amplifiers?
2. What are the Different Types of distortion present in amplifiers and explain them?
3. What are the different types of feed backs?Feedback is nothing but it is a process of returning some part of output signal to the input of the amplifier.
There are two types of feedbacks:
1. Negative feedback
2. Positive feedback
Negative feedback: If feedback signal(returned signal) is in such a way that it reduces net input is called –ve feedback.
Positive feedback: If feedback signal is in such a way that it assists the net input is called +ve feedback.
