Question

A 12KHz message signal with peak voltage 20V is used to modulate a carrier wave of frequency 12MHz and peak voltage 30V. Calculate (i) modulation index (ii) side band frequencies.

Open in App

Solution

Dear Student ,
Modulation index = 20 / 30 = 2/3
Side bands are = 12000 + 12 = 12012 KHz and 12000- 12 = 11988 KHz
