ABSTRACT:
A delay line time compression correlation circuit for correlating two sets of serial data is disclosed, and includes a counter for defining the number of data pairs that have been correlated and the amount of time shift between the two sets of serial data. The two sets of serial data are digital samples of two clipped analog input signals which are simultaneously sampled as a function of the correlation count value. The samples are stored and serially cross-correlated with predetermined time displacements between the two sets of data. The correlation results for each particular time displacement are summed with such total being provided as an output while the correlation for the subsequent time displacement takes place.
