%% Create Signal Source
% Note: This example runs only in R2016b or later. If you are using an earlier release, replace each call to the function with the equivalent step syntax. For example, myObject() becomes step(myObject).
% Create a signal source to output one sample at a time.

src1 = dsp.SignalSource;
src1.Signal = randn(1024,1);
y1 = zeros(1024,1);
idx = 1;
while(~isDone(src1))
    y1(idx) = src1();
    idx = idx + 1;
end

% Create a signal source to output vectors.

src2 = dsp.SignalSource(randn(1024,1),128);
y2 = src2(); % y2 is a 128-by-1 frame of samples
