% Filter one time-series

% Make a filter

% Filter the input data
[a2, f1] = filter(a1,plist('filter', f1));

% Make TF from a1 to a2

% Use MATLAB directly

[txy, f] = tfestimate(a1.data.y, a2.data.y, win.win, Nfft/2, Nfft, a1.data.fs);

% Plot
iplot(t1, t2, plist('LineStyles', {'', '--'},'YErrU',{t1.dy,''}))
