Supervision of Input Signal Channels
First Claim
1. A system configured to monitor a plurality of analog-to-digital converters, comprising:
- a plurality of input channels, each in communication with a different phase of a three-phase electric power delivery system, and configured to receive a plurality of analog signals from the three phases;
a composite signal subsystem configured to generate a composite signal based on the plurality of input channels;
an analog-to-digital converter subsystem in communication with the plurality of input channels and the composite signal subsystem, the analog-to-digital converter subsystem configured to produce a digitized representation of each of the plurality of input channels and a first digitized representation of the composite signal; and
a monitor subsystem in communication with the analog-to-digital converter subsystem and configured to identify at least one error based on the digitized representation of the composite signal and the digitized representations of the plurality of input channels.

Abstract
The present disclosure pertains to systems and methods for monitoring a plurality of analog-to-digital converters. In one embodiment, a plurality of input channels may each be in communication with a different phase of a three-phase electric power delivery system. The input channels may be configured to receive analog signals from the different phases. A composite signal subsystem may be configured to generate a composite signal based on the plurality of input channels. An analog-to-digital converter subsystem may be configured to produce a digitized representation of each of the plurality of input channels and a digitized representation of the composite signal. An analog-to-digital converter monitor subsystem may identify an error in the analog-to-digital conversion based on the digitized representation of the composite signal and the digitized representations of the plurality of input channels.
