FM without noise
Fs = input( enter the value of Fs ) Sampling rate of signal
Fc = input( enter the value of Fc ) Carrier frequency
t = [0:Fs] /Fs Sampling times
x = sin(2*pi*20*t) +2*sin(2*pi*60*t) Channel
dev = input( enter the value of dev ) Frequency deviation in modulated signal
y = fmmod(x,Fc,Fs,dev) Modulate both channels.
z = fmdemod(y,Fc,Fs,dev) Demodulate both channels.
