can some one explain to me why are there M peaks when I plot the fft of a FSK modulated signal, following is the matlab code
M = 4; freqsep = 8; nsamp = 8; Fs = 32;
x = randint(1000,1,M); % Random signal
y = fskmod(x,M,freqsep,nsamp,Fs); % Modulate.
ly = length;
% Create an FFT plot.
plot(abs(fft))
M = 4; freqsep = 8; nsamp = 8; Fs = 32;
x = randint(1000,1,M); % Random signal
y = fskmod(x,M,freqsep,nsamp,Fs); % Modulate.
ly = length;
% Create an FFT plot.
plot(abs(fft))
