I'm new in this forum! ... and I'm not an expert in signal processing! ... So I hope to find help here:-)
I was wondering if someone could point me to an algorithm/technique that is used to compare time dependent signals. Ideally, this hypothetical algorithm would take in 2 signals as inputs and return a number that would be the percentage similarity between the signals.
In other terms I’m looking for a technique that allows to establish a degree of “similarity” between the two signals even if there is a delay or a shift between them. Obviously, if this technique could be implemented in a recursive way or with a small number of point ...it would be great! :-)
Thanks
