Question

In a negative feedback amplifier the input impedance increases if

Answer 1

Negative feedback opposes or subtracts from the input signals giving it many advantages in the design and stabilisation of control systems. Meaning that its signals flow one way only from the output to the input of the system. This then makes the loop gain, G of the system independent of the load and source impedances.

Answer 2

Answer:

System independent of the load and sound
