Claim:
1. An analog to digital (A/D) conversion system with failure identification, comprising: an amplifier configured to receive an input and produce an amplified output injected with at least one identifiable characteristic; an A/D converter configured to receive the amplified output and convert the output to a digital output; a failure identification module configured to determine the existence, non-existence, or variation of the identifiable characteristic in the digital output; a filter configured to filter the digital output to remove the identifiable characteristic from the digital output; and an alert module configured to provide a failure notification based on a determination by the failure identification module that the identifiable characteristic does not exist in the digital output, or has changed in a manner indicative of an A/D failure and/or amplifier failure.
