Which one is increased when a negative feedback voltage is applied to an amplifier? Correct Answer Input impedance
- Feedback is the process by which a fraction of the output signal, either a voltage or a current, is used as an input
- Feedback reduces the overall voltage gain of a system
- Negative feedback also has effects of reducing distortion, noise, sensitivity
- It is improving system bandwidth and input and output impedances
- Increases the input impedance and decreases the output impedance
