the red signal is y = sin(x) + sin(3 * x) and the. the blue signal is y = sin(x) - sin(3 * x) / 3. And in this case the actual correlation of the signal pairsis approx. 44%. By the way, the correlation between the red and the green signalabove is 70.7% while it …
Autocorrelation (for sound signals)
https://pages.mtu.edu/~suits/autocorrelation.html
Autocorrelation (for sound signals) "Autocorrelation" is used to compare a signal with a time-delayed version of itself. If a signal is periodic, then the signal will be perfectly correlated with a version of itself if the time-delay is an integer number of periods. That fact, along with related experiments, has implicated autocorrelation as a potentially important part of signal …
