A Low Speed Correlator
N.H. Farhat · IEEE Transactions on Instrumentation and Measurement · 1967
For the purpose of determining the correlation between two given stationary time functions e1(t) and e2(t), a correlator capable of providing the value of the correlation coefficient was developed. The theory of operation and performance evaluation is discussed. The minimum discernible correlation coefficient of the correlator is found to be about 0.01.
