Fully automated spectral analysis of periodic signals

In this paper, we propose a method that allows to make a fully automated spectral analysis of a periodic signal, including a noise analysis, without any user interaction. The only action required from the user is to provide a data record that contains more than two periods of the signal (no integer number of periods is required). No synchronization between the generator and the data acquisition is needed, and different sampling rates are allowed (no integer number of samples/period is required).
