Method and system for validating video waveforms and other electrical signals

Abstract

Method for validating a single waveform or series of waveforms that are intended for evaluating signals within an automated testing environment. Test signal data is supplied by an external source. The method creates a golden template from a known, good instance of the waveform under test and algorithmically applies it to other waveforms under test to determine compliance. In the application to video waveforms, timing parameters, deflection parameters and image content parameters are simultaneously tested resulting in efficient concrete and tangible results. Instead of providing the known, good instance of the waveform under test to a processor that implements the method, descriptive parameters of the known, good instance of the waveform may be provided to the processor that calculates data points of the expected video waveforms and then determines rules for the waveform based on the calculated data points.
