Abstract
A method and apparatus is disclosed for forming a binary level output signal which has a single transition representative of a threshold crossing in a sensor output signal. The sensor output signal is applied to the inputs of two signal processing circuits, the first of which develops a first signal having a relatively fast transition representing the threshold crossing. The second circuit develops a second output signal that is representative of an integrated version of the sensor signal. In the preferred embodiment, a flip-flop receives the first signal at a clock input and the second signal at a data input. The flip-flop's set input may also receive the second signal. The resultant output signal from the flip-flop has but a single transition representing the threshold crossing, irrespective of noise-induced threshold crossings in the sensor output signal.
