Abstract
A digital filter for time-division multiplexing a set of digital signals has a multiplexer receiving the input signals and selecting one by control signal; a multiplexing digital filter receiving the selected signal and performing a filtering function, which consists of a string of pipeline registers wherein each one delays the input signal a finite time slot; a demultiplexer outputting said filtered signal to one terminal corresponding to the input signal by the same control signal. The method for filtering a set of digital signals matches each digital signal to its own state signals.
