DEFINITION

Classification: 73/861.06

With autocorrelation or cross-correlation detection:

(under subclass 861.05) Subject matter wherein it is determined if a signal (i.e., f1(t)) is noise by correlating it with either another signal (i.e., the solution to cross-correlation in Figure 1) or with itself (i.e., the solution to autocorrelation in Figure 2), where f1(t) and f2(t) are functions of time, t, and t is a period of delay: [figure] [caption]Figure 1 [figure] [caption]Figure 2
