1.Define modulation index.

2.What is the preferable value of modulation index in AM system, high value or moderate value?

Asked by Topperlearning User 9th July 2014, 9:42 AM
Answered by Expert

1. Modulation index(μ) of an AM wave is the ratio of amplitude of modulating signal(A m ) and amplitude of carrier wave(A C).



2. Modulation index is kept less than 1, that is Am

A moderate value of modulation index is desirable so as to avoid distortion in the wave form.
