Demodulation MATLAB code

CODE:

t=0:0.0005:1;

fc=5;

fs=50;

f=5;

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

subplot(3,1,1);

plot( t , m),grid on;

title('Modulating signal');

xlabel('Time');

ylabel('Amplitude');

y=modulate(m,fc,fs,'amdsb-sc',1); 

subplot(3,1,2);

plot(t , y),  grid on;

title('Modulated Signal');

xlabel('Time');

ylabel('Amplitude');z=demod(y,fc,fs ,'amdsb-sc'); 

subplot(3,1,3);

plot(t, 2*z);

ylim([-1 1]);

title('Demodulated output');

grid on;

ylabel('Amplitude');

xlabel('Time');

 Result:

 Result of Modulation
