How fine should you sample in time (and what should the range be) when calculating a spectrum based on some relaxation times ("modes" in physics, not sure about signal processing). I have some relaxation times $\tau$ that span several orders of…

While going through Proakis's Digital Signal Processing (page 21) ,he stated that if a continuous time signal $~x(t)~$ that has been sampled each $~T~$ seconds to produce a discrete time signal $~x(n)~$ then the relationship between the variables…

I'm working on building a system which can detect such patterns by some methods excluding any statistical or frequency domain analysis techniques. How to detect such repetitive pattern for any faulty system which is producing such data? **

Suppose we have a time bounded original signal f(t) where f is nicely behaved, for simplicity we can restrict it to a polynomial. The crux of the problem is that its analytical form is unknown, we only have the sampled values of the signal and its…
