Abstract
A rotational speed estimation method for an incremental encoder includes generating a plurality of pulse signals according to a plurality of square waves, detecting a time duration when the pulse signals reach a predetermined amount, and generating a rotational speed of a disc according to the predetermined amount, the time duration, and the total number of pulses corresponding to one rotation of the disc of the incremental encoder.
