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

keep all files in a folder and run any of the test files.

my_fmdemod(s, fc, fs)

function v_fmd = my_fmdemod(s, fc, fs)

% now i am going  to make a function to demodulate the FM signal, here s is
% the frequency modulated signal, fc and fs are plays same role. the basic
% principle is to make AM from FM, and then demodulate by the same way as
% AM demodulator

% taking the derivatives of the FM signal
s_derv = diff(s);

% now call the function of AM demodulater
v_fmd = my_amdemod(s_derv, fc, fs);

end
