Abstract
Disclosed is a programmable convolver utilizing charge transfer devices. The convolver consists of a signal transform unit, a multiplier unit, and an inverse signal transform unit. The transform unit receives selected segments of successive samples of an input signal, and performs a chirp Z transform without post-multiplication on the samples. The multiplier unit forms product signals from the transformed samples and an arbitrary complex signal H(kw.sub.p). The inverse transform unit receives the product signals and performs an inverse chirp Z transform without pre-multiplication. Digital or analog transfer function generators may be included as part of the programmable convolver to generate the signal H(kw.sub.p).
