my_ammod(m, K, A, fc, fs) here i want to show the method of generating AM signal, here m is the
my_fmdemod(s, fc, fs) now i am going to make a function to demodulate the FM signal, here s is
my_fmmod(m, A , B , C , fc , ... here i am going to show the generation of FM signal by the my_fmmod
test_am() this m file demonstrate the testing of AM modulation demod signal, now i
test_file_am() this is the test file for modulating and demodulatin the music signal of
test_file_fm() by this file i have to take a music file of duration 20 sec, and perform
test_fm() now i am going to test the my_fmmod file by making modulating, and carrier

my_ammod(m, K, A, fc, fs)

function s= my_ammod(m, K, A, fc, fs)
%here i want to show the method of generating AM signal, here m is the
%modulating signal, K is the constant factor, A is the carrier eamplitude,
%fc is the carrier ferquency, and fs is the sampling ferequency here s iis
%defined as  s = A(1 + K*m(t))cos(2*pi*fc*t)

 % show the warning messege when K is too large
 
 if(K*max(abs(m)) > 1)
     warning('warining K*m(t) must me <= 1');
 end
 
 %calcualting the time vector from sampling frequency and signal
 t = linspace(0, (length(m)-1) / fs, length(m));
 
 %process for computing AM signal
 s = A*(1 + K*m).*cos(2*pi*fc*t);%+ rand(length(fs));

 end
