# 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.Determinea) Modulation Indexb) 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
$\mu =\frac{{A}_{m}}{{A}_{c}}=\frac{10}{20}=0.5$
(b) The side bands will be at
