- b)Increases
- c)Has no effect on
- d)Destroys
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
The negative feedback _______ input impedance of an amplifier.a)Decrea...
- Negative feedback reduces the gain of the system by a factor of (1 + Aβ).
- Thus, because of feedback configuration, voltage gain will be decreased by a factor (1 + Aβ).
- Voltage series type feedback tells us that the input of the system is series connected with the feedback loop and series connection corresponds to increased impedance.
- Therefore the input impedance will be increased by a factor (1 + Aβ).
