ABSTRACT:
The bipolar signals produced, for example, by a magnetic transducer which senses the positions of slots in a ferromagnetic damper wheel, are integrated. The resulting integrated signal has peaks at times corresponding to the zero crossings of the bipolar signals and is of lower, relatively constant, amplitude at other times. The peaks may be used to prime an otherwise disabled circuit in the path through which signals indicative of zero crossings are transmitted to thereby discriminate between zero crossings of interest (those of the bipolar signals) and those due to noise.
