A message signal of frequency 10 kHz and peak voltage of 10 volts is used to modulate a carrier of frequency 1 mHz and peak voltage of 20 volts Determine (a) modulation index, (b) 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 (1000-10 kHz)
= 990 kHz.
