A message signal of frequency 10 KHz and peak voltage of 10V is u sed to modulate a carrier of frequency 1 MHz and peak voltage of 20V. The frequency of the side bands produced is

Text Solution

Verified by Experts

(a) Modulation index `= 10//20 = 0.5`
(b) The side bands are at `(1000 + 10 kHz) = 1010 kHz and (1000-10 kHz) = 990 kHz`
