Window sampling
First argument is the window length wl, second is the sampling interval t. The output list should contain (min (truncate (T/t) wl)) samples, where T is the time the signal function has been running. This requires some care in case of sparse sampling. In case of sparse sampling, the current input value is assumed to have been present at all points where sampling was missed.
