Both CCDs and BBDs are examined and compared with competing technologies. The primary emphasis in this program was placed on the potential of these devices for low data rate, spread-spectrum, matched filtering. However, in addition, consideration was also given to other applications such as low-pass and band-pass filtering, analog delay, telephone line equalization, and single sideband modulation. Theoretical analysis is given of limitations, behavior, and tradeoffs among CTD parameters of interest, and noteworthy general characteristics of the technology are discussed.
