Abstract
Disclosed are systems and methods for identifying and reporting failures of an analog to digital (A/D) conversion system. An A/D conversion system includes a test signal generator configured to generate a test signal including an identifiable characteristic, an A/D converter configured to convert an analog signal measured at an input of the A/D converter to a digital output, and signal injection circuitry configured to inject at least a portion of the test signal from the test signal generator as an injected signal into the analog signal using trace-to-trace crosstalk. A method includes determining whether the digital output generated by the A/D converter indicates the identifiable characteristic.
