Applicators of negative feedback to an amplifier will?

Options are:
a- Improve linearity.
b- Improve the signal to noise ratio.
c- Reduce the bandwith

a. Absolutely true. You can use diode in a feedback loop to linearize it nicely. Reference 1 discusses the use of negative feedback to improve linearity.

b. False. See reference 2. The noise is internally generated and is amplified just like the input signal. The negative feedback will reduce both the noise and signal equally.

c. True. Negative feedback does reduce the bandwidth of an amplifier.
