# As a result of the introduction of negative feedback which of the following will not decrease

As a result of the introduction of negative feedback which of the following will not decrease

#### SOLUTION

If the feedback fraction is opposite in value or anti-phase to the input signal, then the feedback is said to be Negative Feedback or degenerative feedback. If the output of the system changes for any reason, then negative feedback affects the input in such a way as to counteract the change.

The feedback amplification factor is given by:

${A_f} = \frac{A}{{1 + A\beta }}\$

where,

A is open-loop gain

Aβ is the loop gain.
