How do you compare similarity between two signals?
For measuring the similarity between two temporal signals, you can try using Dynamic Time Warping (DTW). DTW constructs a distance matrix between the two signals and tries to find minimum distance the two signals. If the two signals are identical, then distance is zero.
Is basically used to find the similarity between the signals?
Cross-correlation is a measure of similarity between two signals.
How do you know if two signals are correlated?
In words, we compute a correlation by multiplying two signals together and then summing the product. The result is a single number that indicates the similarity between the signals x[n] and y[n]. What values can C(x, y) take on, and what does this tell us about the signals x[n] and y[n]?
