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.
