FAQs on Block Diagram of Feedback Amplifier Video Lecture - Analog and Digital Electronics - Electrical Engineering (EE)

1. What is a feedback amplifier in electrical engineering?
Ans. A feedback amplifier is an amplifier that uses a portion of the output voltage or current to feed back to the input in order to stabilize or modify the amplifier's performance.
2. What is the purpose of using feedback in an amplifier circuit?
Ans. The purpose of using feedback in an amplifier circuit is to improve stability, bandwidth, input and output impedance matching, and reduce distortion.
3. What are the types of feedback used in amplifier circuits?
Ans. The two main types of feedback used in amplifier circuits are positive feedback, which increases the gain of the amplifier, and negative feedback, which reduces the gain of the amplifier.
4. How does negative feedback affect the performance of a feedback amplifier?
Ans. Negative feedback in a feedback amplifier reduces the gain of the amplifier but improves stability, bandwidth, and reduces distortion, making the amplifier more accurate and reliable.
5. What are the advantages of using feedback in amplifier circuits?
Ans. Some advantages of using feedback in amplifier circuits include improved linearity, reduced distortion, increased bandwidth, improved stability, and better noise performance.
