Displaying (possible) periodic data
I'm hoping that this is the correct group of threads to submit to, if not please move it. I'm looking for some advice, I don't want a problem solved just a pointer in the right direction.
I've been given a bucket-load of numerical data which I believe comes from a periodic source/output. I want to make sense of this data, that is perhaps find reoccuring patterns/structures/periods etc... Would I be barking up the wrong tree if I thought Fourier series would have something to do with it?
I'm not too great at statistics, or modeling via mathematics so help would be much appreciated.
