METHOD OF INDICATING CORRELATION BETWEEN MULTIPLE SIGNALS, AND TEST MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To generate a trigger event on the basis of a covariance value or a correlation value between multiple signals.;SOLUTION: A reference signal is digitized and stored, and is used as a reference in comparing with input signals in real time. The average value of the input signals and the pre-stored reference signal are generated in order to generate a correlation value. A threshold detection unit triggers a test measurement device when a covariance value or the correlation value exceeds a threshold.;COPYRIGHT: (C)2014,JPO&INPIT
