Abstract

Charge-coupled devices (CCD's) are analog sampled-data delay lines which can be used to implement many of the filtering functions required for transform encoding in video bandwidth reduction. The CCD transversal filter is a fundamental building block which is particularly cost effective in terms of it's simplicity and versatility. In particular it can be used to perform the Fourier transform of video signals by means of the chirp z-transform (CZT) algorithm. CCD's have performance limitations compared to digital filters, but for applications which fall within their performance ranges, CCD's offer advantages of lower cost, smaller size, lighter weight, lower power and improved reliability over digital filters.
