An expression is given for the most general input–output map associated with the members of a certain important large family of causal linear shift‐invariant systems with bounded inputs. This expression is a function‐space limit of a convolution. Also given is a necessary and sufficient condition under which the limit can be written as a convolution with an integrable impulse‐response function. Related material concerning engineering education, as well as additional results for other sets of inputs, is also given. Copyright © 2005 John Wiley & Sons, Ltd.
