Abstract
A Transistor Resonant Characteristic Sensor (TReCS) includes a sensing element positioned along electronic equipment so that the sensing element is electromagnetically coupled to the electronic equipment. The sensing element includes a coil. The sensing element is configured to detect magnetic oscillations associated with a characteristic signal generated by the electronic equipment. The TReCS sensor further includes an evaluation circuit connected to the sensing element for monitoring health state of the electronic equipment. The evaluation circuit includes one or more processing elements configured to diagnose health state of the electronic equipment based on extracted baseband information associated with the characteristic signal.
