CCD multi-function processor test bed

This report describes the Charge-Coupled Device (CCD) Multi-Function Processor Test Bed developed to support the test and evaluation of, and experimentation with, second- and third-generation CCD Programmable Transversal Filters (PTF) developed for RADC/ESE by Texas Instruments. The test bed consists of the PTF Module and PTF Exerciser Module. These modules provide the circuitry necessary to program, operate, control, and interface the PTF device. The present level of performance justifies continued experimentation and investigations into applications of the PTF as a generic signal processing module. Two areas that will continue to be pursued in FY82 include comparing the performance of the PTF configured as an adaptive equalizer in a wideband HF system against an existing all-digital equalizer and, secondly, application of several PTF Modules as a matched filter in a spread-spectrum modem.
