AN2301: Tachometer using a Switched Reluctance Rotation Sensor

This Application Note describes a tachometer using a switched reluctance rotation sensor. Besides providing information about rotational speed, the tachometer separates the marker signal, which is intended to measure shaft absolute angle. The device can be used in vehicles to measure engine rotation speed and detect the top dead-center position of the crank/camshaft.
