fs = 8000;

vk = 1:2000;

amp = kaiser(length(vk),20).' * .5;

f1 = 300;
f2 = 1000;

[N,M] = size(A);

x = zeros(1,8000);
for n = 1:N
    for m = 1:M
        if A(n,m)=='1'
            f = f1;
        else
            f = f2;
        end
        x = [x sin(2*pi*f/fs*vk) .* amp zeros(1,2000)];        
    end
    x =  [x zeros(1,8000)];
   
end
