Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics.

Abstract

A difficulty that electronic and electrical engineering students traditionally have in reconciling taught material covering convolution and impulse responses revolves, at least partly, around the problem of dimensions or units. It is suggested that confusion can be minimised, or avoided, by making explicit reference to the units that an impulse response takes in the context of an electronic or electrical system and explaining the origin of these units physically.
