Abstract
A method of debouncing a variable frequency step signal is provided. The method includes the steps of: (a) determining a first period in oscillations of the variable frequency step signal and applying a first debounce time to debounce oscillations in the variable frequency step signal, (b) detecting a second period in the oscillations of the variable frequency step signal, (c) calculating a second debounce time as a fraction of the first period, (d) applying the second debounce time to debounce oscillations having the second period, and (e) repeating the steps (b)-(d) for debouncing successive oscillations of varying periods in the variable frequency step signal.
