Abstract
Several special‐purpose devices capable of performing correlation measurements have been described in the literature over the past few years. While the expected outputs of these devices have been shown to equal the required correlation function, their intrinsic sampling errors have apparently not been investigated. Two such important devices are the modified relay and polarity‐coincidence correlators. Variances for their measurement errors are derived in this paper. The dependence of the sampling error on the information content of the input processes and on the type of auxilliary signal is also considered. The analysis is confirmed by the experimental results.This publication has 3 references indexed in Scilit:
