ABSTRACT:
A method and circuit for reducing by electrical runout subtraction, the runout signal portion of a composite runout signal and vibration signal, which runout subtraction signal is provided by a pre-programmed digital memory circuit module, PROM, that is selectively inserted into the circuit for a given rotating shaft. The PROM is accessed by a phase lock loop, master dynamic clock, synchronized to the tachometer signal, which provides the subtract signal in digital form that is changed to an analog signal and then fed with the composite signal to a differential amplifier circuit that subtracts the PROM waveform from the composite signal. In one mode the subtract amplifier circuit is inhibited in operation when the tachometer signal falls below a given CPM, or when the tachometer signal is lost.
