The boss of electronics [episode-6] is the feedback key, which tells, how many types and requirements

Assalamu Alaikum,

I hope everyone is very good. I came to you about something about electronics. Let’s start talking without talking. We will know about Feedback Amplifiers today.

What is feedback?
The method in which the output of a circuit is applied to special input part of the signal is called Feedback.

Feedback Generally two types namely:
1 / Positive Feedback
2 / Negative Feedback

Positive Feedback: If some parts of the output signal are mixed with the input signal,
She called positive feedback.

Positive Feedback is again two types, namely:
(A) Positive voltage feedback.
(B) Positive Current Feedback.

Negative feedback: If some part of the output signal is mixed in the opposite phase with the input signal,
Call him a negative feedback.

Negative feedbacks are of two types, namely:
(A) Negative voltage feedback.
(B) Negative Current Feedback

Below are different types of feedback:
1 / Voltage Feedback: If the feedback power is proportional to the output signal voltage,
The voltage is called feedback.

2 / Current Feedback: If the feedback power output is proportional to the output signal,
As the current feedback says.

3 / Series Feedback: If the feedback power is given in the input signal sequence, then,
Say series feedback.

4 / Energy Feedback: If the feedback power is given in parallel to the input,
Power or Shunt Feedback.

What are the Advantages of Negative Feedback:

Advantages of negative feedback are given below-
1 / reduce amplifier distortion.
2 / amplifiers gain stabilization or stability.
3 / Amplifier frequency frequency increase.
4 / amplifier circuit increases stability or stability.
5 / Amplifier increases the circuit’s input impedance and reduces output impedance.

Differences Between Positive Feedback and Negative Feedback?
Positive Feedback                                                    Negative feedback
1. Signal in positive feedback.     1. Inactive feedback is provided with opposite phase signal.
2.feedback output signal increases strength and gain.2.feedback output signal can reduce the power and gain.
3. Oscillation is organized.          3. Oscillation is not organized.
4. Agentive Process                  4. Dissociative process.
5. Output stability is reduced.     5. Output stability increases.
