Abstract
A method and apparatus for testing automotive electronic control units and batteries and other equipment for identification and performance purposes utilizes neural networks to effect waveform analysis on a digitized signal. Identification of electronic control units is by means of correlation of resultant waveform data with corresponding data on known units. Battery testing is by waveform analysis of the battery current during transient connection of a load by a transistorized switching circuit. In both cases the method of testing includes a network learning stage and an ensuing recognition test routine for characteristic waveforms.
