A message signal of frequency 10kHz and peak voltage 10 V is used to modulate a carrier of frequency 1 MHz and peak voltage of 20V.Determine
a) Modulation Index
b) the side bands produced
Given
For Message signal'
Frequency, fm = 10 kHz
Peak voltage, Am = 10 V
For carrier frequency
Frequency, fc = 1 MHz = 1000 kHz
Peak voltage, Ac = 20 V
(a) Modulation frequency is given by
(b) The side bands will be at
