A system for intrinsic evolution of linear and non-linear filters

Abstract

A system for exploring intrinsic evolution of linear and non-linear filter systems is described. It consists of a testbed topology of operational amplifiers and linear or non-linear passive components together with a control and measurement system for selecting different values and layouts of components and testing the resulting circuit. The results of each measurement can be used by an evolutionary algorithm to search for a good match to a target response.
