Abstract
Iterative electronic circuits - that is, circuits whose behaviour can be described by a mapping in which time is not explicitly present - are investigated, and particular attention is paid to those circuits which can be shown to display chaotic behaviour. Examples emanating mainly from the fields of power electronics and digital electronics are discussed. The emphasis is on the derivation of analytical results wherever this is possible, although numerical calculations have also been much relied upon. Some of these results are supported by experimental investigations. Many of the results are presented in the form of diagrams. The implications of chaotic behaviour for electronic engineers have been indicated. A brief discussion of the relation between iterative circuits and circuits that are described by non-linear differential equations is included.
