Question

An FM signal with a deviation is passes through the mixer, and has its frequency reduced five fold. The deviation in the output of the mixer is-A-&Delta;B-5&Delta;C-&Delta;/5D-indeterminantE--A-&Delta;

APTITUDE CRACK · Accepted Answer

The correct option is  A &Delta;  Δf (frequency deviation) is independent of fm , Δf depends only upon amplitude of message signal. Δf = kf.Am .
