Question:
A Negative feedback:
A Negative feedback:
Show Hint
Negative feedback improves stability, bandwidth and linearity, but reduces gain.
Updated On: May 19, 2026
- improves frequency response and nonlinearity of operation of the amplifier
- increase the noise level of output
- increases the transfer gain of a transistor
- all of these
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Negative feedback means a part of the output is fed back to the input in opposite phase.
Step 1: Effect on frequency response.
Negative feedback improves the frequency response of an amplifier. \[ \text{Frequency response improves} \]
Step 2: Effect on distortion and nonlinearity.
Negative feedback reduces distortion and improves linearity of operation. \[ \text{Nonlinear distortion decreases} \]
Step 3: Effect on noise and gain.
Negative feedback generally reduces noise and stabilizes gain, but it does not increase transfer gain.
Step 4: Final answer.
Thus, the correct statement is that negative feedback improves frequency response and operation of the amplifier. \[ \therefore \text{Correct Answer is (A)} \]
