Paper Abstract

A digital correlator/spectrum analyzer has been developed for the analysis of signals of 0-5 MHz bandwidth. The simple architecture includes two analog input channels (allowing crosscorrelation and cross-spectral analysis), 8-bit quantization, correlation calculation with up to 128 lags, and DFT output circuitry. Correlation functions and spectra are produced at intervals of 1 ms or longer, in both analog and digital form. Pipeline architecture allows unity duty cycle operation, with no loss of data between spectra. Extensive use of parallelism and LSI arithmetic units makes possible computing power of over 600 million operations per second in an 8" high package which requires about 200 watts.
