An illuminating exercise in digital signal compression Discrete convolution often leads to a sequence which has greater duration than either of the two participating sequences, sometimes lending the incorrect impression that such spreading is inevitable. A signal compression counterexample, which illustrates the interplay between zero-insertion interpolation and pole-zero cancellation effects, is explored from several intuition-reinforcing standpoints.
