So I'm having some troubles with a signal that's been sampled but where the samples don't have consistent intervals. I've been looking into the NFFT (in python) as a starting point but I'm a complete noob with signal processing so I'm not really getting anything out of it.
So I have one array with the sample values and another with the corresponding timestamps. But I really have no idea how to get the spectrum out of it. I've done the first part as described here.
Sorry about the sparse question.
