I have this fsk function code:
function [x]=fsk_encode(b,s,f0,f1,N,Fs,K)
% b= bit sequence vector
% s(1)= output level for 0
% s(2)= output level for 1
% N= length of bit sequence
% Fs= Sampling frequency
y=zeros(1,N*K); %Setup output vector
%for each bit calculatee the rando samples
for n=1:N
for k=1:K
t = (k - 1) / Fs;
if(b(n)==0)
y((n-1)*K+k)=cos(2*pi*f0*t); % pulse=0
else
y((n-1)*K+k)=cos(2*pi*f1*t); % pulse=1
end
end
x=y; %set output
end
