Abstract: A multichannel filter architecture having an external sequencer to provide timing and control signals which enable the filter to function as a plurality of filters because of its multiplexing operation. The filter samples input data and applies the filter functions to each sample. There may be a single input composed of either a single input or multiple time-multiplexed inputs. The multiplexing functions the same way independent of the input form. The filter functions are programmable and reprogrammable, allowing them to be changed by software rather than a redesign of hardware for a new filter function.
