Abstract

A system and a method for detecting a low-frequency periodic signal (LFPS) include at least one comparator performing a threshold comparison on an analog input signal over a period of time. A sampling circuit generates digital signals by sampling an output of the at least one comparator. A digital detection circuit applies a set of detection rules to the digital signals. The detection rules are configured to detect a presence or an absence of an LFPS based on predefined criteria concerning characteristics of the digital signals.
