Abstract:
A filter, comprising:n+2mâˆ’1 track and hold circuits, n and m being integers, each coupled to receive an input signal and to produce a sampled version of the input signal; a crosspoint switch matrix configured to receive n+2mâˆ’1 sampled versions of the input signal from the track and hold circuits and to produce n+mâˆ’1 selected samples; and m parallel output paths, each coupled to receive a subset n of the selected samples from the crosspoint switch matrix such that a first one of the output paths receives first through nth ones of the selected samples, a second one of the output paths receives second through n+1th of the selected samples, and so on for all m output paths with an mth one of the output paths receiving an mth through n+mâˆ’1th of the selected samples, each parallel output path being configured to produce a respective output signal which is a sum of products of the subset of selected samples and respective filter coefficients.
