Abstract
A sensor sampling system comprises a base station and a field unit. The field unit receives a quasi-periodic signal representing machine parameters monitored by a machine sensor, and samples a first portion of the quasi-periodic signal to generate a first reference waveform. The field unit subsequently samples a second portion of the quasi-periodic signal to generate a first sample waveform. Finally, the field unit generates a first delta data set representing a difference between the first reference waveform and the first sample waveform and wirelessly transmits a representation of the first delta data set for reception by the base station.
