Abstract
An electrical meter (M) installed at a facility (F) supplied electrical power by a utility's (U) electrical distribution system (EDS) utilizes a two-way automatic communications system (TWACS) for receiving messages from the utility sent over the electrical distribution system using the TWACS. An improvement to the meter comprises reconfiguring existing components installed in the meter to function as an analog-to-digital (ADC) converter so to facilitate processing of powerline waveforms (WF) propagated through the electrical distribution system by application of a signal based detection algorithm. This improves detection of signal elements comprising a message sent via the TWACS and by other means and incorporated in the electrical waveforms thereby reducing occurrence of a false synchronization with the message elements so a content of a message is readily ascertained by the meter.
