For analyzing the feedback amplifier, it is necessary to go through the following steps.

Step 1 : Identify topology ( Type of feedback)

1. To find the type of sampling network

(i) By opening the output if feedback signal becomes zero, then it is called "voltages sampling"

(ii) By shorting the output loop if feedback signal becomes zero, Then it is called "Current Sampling"

2. To find the type of mixing network

(i) If the feedback signal is subtracted from the externally applied signal as a voltage in the input loop, it is called "Series Mixing"

(ii) If the feedback signal is subtracted from the externally applied signal as a current in the input loop, it is called "Shunt Mixing"

Thus by finding the type of sampling network and mixing network, type of feedback amplifier can be determined. for example, If amplifier users a voltages sampling and series mixing, then it is called a voltages series amplifier

What is feedback circuit?

A circuit in which output feeding back to input to increase or decrease the gain is called feedback circuit. Basically part of output feeding to input in such way that it increase the value of input is positive feedback and it also increase gain of circuit and similarly to it when part of output feeding to input in such way that it decrease the value of input is called negative feedback it also decrease the gain of circuit.

Why negative feedback amplifier is preferred to positive feedback amplifier?

The negative feedback tends to stabilize the circuit; positive feedback would make it more unstable. For example, the "beta" of a transistor OF THE SAME SERIES - this is basically the amplification factor - may vary between 100 and 1000. With negative feedback, the circuit is hardly affected by these changes in beta - at the cost of a reduced amplification.

What is effect of an unbypassed resistor on the common emitter amplifier circuit?

An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
