Amplitude of a Wave

A signal of ...

Question

A signal of $5 k H z$ frequency is amplitude modulated on a carrier wave of frequency $2 M H z$ . What are the frequencies of the side bands produced?

Open in App

Solution

Given - $f_{m} = 5 k H z, f_{c} = 2 M H z = 2000 k H z$
Now frequency of upper side band ,
$f_{c} + f_{m} = 2000 + 5 = 2005 k H z$
frequency of lower side band ,
$f_{c} - f_{m} = 2000 - 5 = 1995 k H z$

Q. Define modulation index. Why is it's value kept, in practice, less than one?
A carrier wave of frequency 1.5 MHz and amplitude 50 V is modulated by a sinusoidal wave of frequency 10 kHz producing 50% amplitude modulation. Calculate the amplitude of the AM wave and frequencies of the side bands produced.

Q. (a) How is amplitude modulation achieved ?
(b) The frequencies of two side bands in an AM wave are 640 kHz and 660 kHz respectively. Find the frequencies of carrier and modulating signal. What is the bandwidth required for amplitude modulation ?
