MATLAB CODE FOR MODULATION

CODE:

t=0:0.0005:1;

fc=50;

fs=120;

f=5;

m=sin(2*pi*f*t);

subplot(3,1,1);

plot( t , m),grid on;

title('Modulating signal');

xlabel('Time');

ylabel('Amplitude');

c=sin(2*pi*50*t);

subplot(3,1,2);

plot( t , c),grid on;

title('Carrier signal');

xlabel('Time');

ylabel('Amplitude');

y=modulate(m,fc,fs,'amdsb-sc',1); 

subplot(3,1,3);

plot(t , y),  grid on;

title('Modulated Signal');

xlabel('Time');

ylabel('Amplitude');xlabel('Time');

ylabel('Amplitude');

Output:
