The first section of the report describes charge-coupled device CCD characteristics such as signal input and output, tap weighting, frequency response, dispersion, dynamic range, linearity, clocking, etc. This is followed by a discussion of basic CCD building blocks i.e., series inseries out SISO, series inparallel out SIPO, and parallel inseries out PISO for discrete analog signal processing DASP in which discrete analog samples are transported with an electrically alterable time delay and analog weighted. DASP is contrasted with conventional digital signal processing DSP in the remainder of the report and illustrations are presented from representative systems, such as radar, sonar, and communications, to indicate the dramatic savings in cost, weight and volume, and power. A section of the report is devoted to transversal filters and the effects of tap weights and tap weight errors on filter response. Modified author abstract
