A Real-Time Digital Signal Analyzer Correlator Averager Power Spectral Density Analyzer

Subramaniam Ganesan, Girija Gopalrathnam, M Renukadevi

Abstract

The digital signal analyzer described here computes the values of auto-and cross-correlation functions, recovers signals buried in noise, and computes cross-and auto-power spectral density at 100 equally spaced points on the time-delay axis or frequency axis. The results are presented on an oscilloscope or on an X-Y recorder.
