Abstract
An interface for processing a variable reluctance sensor signal provided by a variable reluctance sensor including an integrator, an arming comparator and a detect circuit. The integrator includes an input for receiving the variable reluctance sensor signal and an output providing an integrated signal indicative of total flux change of the variable reluctance sensor. The arming comparator compares the integrated signal with a predetermined arming threshold and provides an armed signal indicative thereof. The detect circuit provides a reset signal after the armed signal is provided to reset the integrator. A corresponding method of processing the variable reluctance sensor signal is also described.
