Abstract
Improvements introduced in the object of the main patent no. 339,686, granted on april 19, 1968, by: "a procedure to determine the correlation between two random quantities available in analog form", improvements that, being the random magnitudes x and y, they comprise the conversion in the form of samples, by modulation of impulses in width, of the random quantity y to delay, the formation, from each sample, of (N-1) delayed samples that represent the magnitude y, in instants t- 0r, t-20r .......... T - (N-1) 0 r, the multiplication in parallel, by the successive values of the other random quantity x of the sequence of samples representing the quantity y at the instant ty (N-1) successions of delayed samples, by modulation in amplitude of the pulses already modulated in width, the determination, in parallel of the average values of the surfaces of the doubly modulated pulses of each sequence, finally, the indication of said goes mean values, these improvements being characterized because they also include the sampling of the random quantity x at a frequency fr such that: (see formula) (Machine-translation by Google Translate, not legally binding)
