Convolutional architectures for spectrum analysis employing CCD programmable transversal filters

Use of a Programmable analogue transversal filter, implemented as a monolithic charge-coupled device, as a basic signal processing element is presented. The application of such a device in waveform convolution is discussed and architectures which take advantnge of the programmable nature of the device are emphasized. Fourier transform algorithms which demand waveform convolution are shown to be efficiently realized with CCD technology and practical results are presented.
