Abstract:
A method and system acquires a set of samples of a periodic signal at a constant sample rate in a primary memory, calculates a variance between the set of samples and an ideal set of samples to create a variance data set, stores the variance set into a secondary memory, concatenates each variance data set to create a concatenated data set, statistically processes the concatenated data set, and presents the statistically processed data.

A method and system acquires a set of samples of a periodic signal, and calculates a variance between the set of samples and an ideal set of samples to create a variance data set. The method and system further calculates an FFT of the variance data set, filters the calculated FFT of the variance data set, calculates an inverse FFT on the filtered data set, and measures the resulting time domain signal.
