ABSTRACT:
Methods for processing waveforms may include decimating an over-sampled waveform by identifying samples for which the sample's position within a data period indicates that is closest to a selected time within a data period. In some example applications, the selected time may be determined as a preferred time to sample the waveform within a data period. In an illustrative example, a sequence of samples representing an over-sampled waveform may be reduced by identifying a sample in each data period that is closest in time to the selected time. In another illustrative example, a sample within each data period may be identified if it falls within a range that is a function of the selected time within the data period and an integral ratio of a sample period to the data period. The identified samples may be used to reconstruct the original waveform with fewer samples than the over-sampled waveform.
