Question

A message signal of freuency 10 kHz and peak voltage of 10V is used to modulate a carrier wave of frequency 1 MHx and peak voltage of 20 V. Determine.(a) modulation index, (b) the side bands produced.

Answer 1

Answer:

Hey Buddy here's ur answer

Answer 2

Modulation index = Am/Ac
= 10/20
= 1/2 = 0.5
Side bands produced are Fm+Fc and Fm-Fc
So they are 1010 kHz,990 kHz
