Lab Title: Frequency Modulation of Message Signal And


Carrier Signal
Introduction:
Frequency Modulation is a fundamental technique in modern communication,
allowing the transmission of high-quality audio and data signals by varying the
carrier frequency according to the message signal's amplitude.

Equipment:
• MATLAB software
• PC
MATLAB Coding:
clc
F=5;% message signal
F1=50; % carrier signal
t=0:0.001:1;
A=10;% amplitude
beta=10;
message=A*sin(2*pi*F*t);% message signal
carrier=A*sin(2*pi*F1*t); % carrier signal
modulate=A*cos(2*pi*F1*t+beta*message);
subplot(3,1,1)
plot( t , message)
title('M Signal');
subplot(3,1,2);
plot(t,carrier);
title('C Signal');
subplot(3,1,3);
plot(t, modulate);
title( ' Modulated output Signal' ) ;
