How do you measure similarity between two signals?

Cross-correlation is a measure of similarity between two signals. It works by sliding one signal across another and finding the optimal match.

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]?

How do you find the similarity between two signals in Python?

Whenever you need to find similarities between two signals, datasets, or functions, cross-correlation is one of the tools that you should try. Cross-correlation between sine & cosine function. Cross-correlation has tons of applications. Investors use it to check how two stocks or assets perform against each other.
