A message signal of frequecy 10 kHz and ...

A message signal of frequecy 10 kHz and peak voltage 10V is used to modulate a carrier wave of frequency 1 MHz and peak voltage 20V. Determine :
(i) The modulation index,
(ii) The side bands produced .

Text Solution

Verified by Experts

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