MATLAB CODE FOR FM MODULATION

MATLAB CODE FOR FM MODULATION:

Ac=1;

fc=1;

Am=1;

fm=0.1;

kf=1.5;

B=kf*Am/fm;

t=[0:0.1:20];

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

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

FMt=Ac*cos(2*pi*fc*t+B*sin(2*pi*fm*t));

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(FMt);

ylabel('FM signal');

grid on;
