Abstract
A method and system for time sharing N consecutive half-band decimating-by-2-filters using a single filter. Aspects of the method may comprise selecting a latched input signal and filtering, via a single decimating filter, the selected latched input signal to generate a first output signal. The method may also comprise latching the fed back portion of the first output signal. This latched signal may also be filtered by the single decimating filter to generate at least a second decimated output signal. A final output signal may be generated by latching at least one of the first output signal and the second decimated output signal. The final output signal may be latched utilizing at least one of a plurality of clocking signals.
