A METHOD FOR ANALYZING COMPLEX SIGNALS |
摘要 |
A test system and method for comparatively analyzing complex signals especially those composed of combinations of pulsed signals related to the operational status of apparatus whose operational status is to be determined, is disclosed. In the preferred embodiment a probe, preferably a capacitive probe, is utilized to sense the electric field generated by electrical apparatus. The output signal of the probe is periodically sampled to generate an array of digital signals. This array is processed using Walsh transformations to generate a reference Walsh transform. A second data base is then generated by similarly sampling the electric field generated by an apparatus whose operational status is to be determined. The second data base is then processed to generate a comparison Walsh transform. The operational status of the apparatus whose operational status is to be determined, is then determined by comparing these Walsh transforms. |
