- Hello to all.I have a signal that contains both periodic and non-periodic parts, in the same temporal slice. How can i detach these two parts in two differents signals?To clarify, the signal that i see incorporates both parts throughout all the spectrum. Thanks.

What knowledge do you have about the periodic part? It is a single frequency, or a superposition of frequencies in some narrowband? If yes to either, you can implement a bandpass filter.
Of course if your nonperiodic component is a broadband, then yes, it will contribute energy throughout the spectrum, but by bandpass filtering you can greatly improve the signal to noise ratio.
