Multirate single-stage and multistage structures for high-speed recursive digital filtering

Multirate single-stage and multistage structures for highspeed recursive digital filtering are introduced. They can be used for arbitrary bandwidths and to increase the speed to an arbitrary level. Most of the filtering is performed at a lower sampling rate than that of the input and output rates which results in a low computational complexity. Design examples are included for demonstration.
