MATLAB CODE FOR AMPLITUDE MODULATION

MATLAB CODE:

clc;

Ac=2;

fc=.9;

Am=.5;

fm=.05;

Fs=100;

ka=1;

t=[0:0.1:50];

ct=Ac*cos(2*pi*fc*t);

mt=Am*cos(2*pi*fm*t);

DSBAMt=ct.*(1+ka*mt);

subplot(2,2,1);

plot(mt);

ylabel('message signal');

grid on;

subplot(2,2,2);

plot(ct);

ylabel('carrier');

grid on;

subplot(2,2,3);

plot(DSBAMt);

ylabel('DSBAM signal');

grid on;
