Abstract
Systems and methods for identifying and reporting failures of an analog to digital (A/D) conversion system are presented. The systems and methods may detect and report a problem of input circuitry of an A/D converter and/or an A/D converter itself. For example, an identifiable characteristic can be introduced into the input signal provided to an A/D converter. The A/D converter may output a digital value that includes the identifiable characteristic of the A/D converter input. A monitoring system may determine and/or report a change in, or a failure of, the A/D converter or input circuitry thereto, based on the identification, non-existence of, or variation in the identifiable characteristic in the digital output.
