Abstract:
1. An electronic device comprising: a component configured to receive a data signal and process data from the signal through a series of circuit layers, beginning with a first circuit layer configured to initially receive the data signal, and ending with a second circuit layer configured to perform an application on data from the data signal, one of the series of circuit layers outputting from the component an error signal containing an error indication, the error signal being generated substantially concurrent with detection, by the one of the series of circuit layers, of a data error occurring in the data signal; a lead configured to convey a noise signal containing noise indications substantially concurrent with noise produced by a noise source of the electronic device; and processor circuitry configured to receive the error signal and the noise signal, and configured to compare timing of the error indication in the error signal and the noise indications in the noise signal, wherein the processor circuitry is configured to produce an output signal identifying the noise source as a possible cause of the error indication if the error indication has a predetermined timing relationship to the noise indication, and wherein the predetermined timing relationship requires the noise indication to be no more than a predetermined amount of time prior to the error indication.
