Abstract
A method for extracting a sought signal from a noisy signal. The method includes sampling a plurality of samples in a series of cycles of the noisy signal wherein each sample having an n-bit sampled value (n≥1), giving rise to a plurality of samples each associated with a respective cycle of the series, wherein each sample is sampled at time T relative to the origin of the respective cycle. The method further includes associating data indicative of the plurality of n-bit samples to N bins according to the corresponding sampled values, wherein N is a function of n, and calculating data indicative of a number of samples for each bin, giving rise to data indicative N-bins histogram or normalized N-bins histogram. The method further includes determining the signal value based on the data indicative of the N-bins histogram or normalized N-bins histogram.
