Abstract
Methods and apparatus for providing a position sensor to sense the position of a ferromagnetic target and generate a target position signal, a scaling block to receive the target position signal, and a digital RC filter to generate an output using bit shifting for dividing by some factor of two, wherein all division for computations in the RC filter are performed by bit shifts.
