Abstract
A filter for high speed digital signal processing. In one embodiment the filter includes a linear, phase-B, interpolating cubic spline filter having a pre-filter section and an interpolating post-filter section. The pre-filter section may be formed to implement any one of a 1-4-1 cubic spline function, a 2-5-2 cubic spline function or a 1-2-1 cubic spline function. The post-filter may be formed using a plurality of running average filters arranged in a cascade (i.e., serial) fashion. The filter can be constructed using significantly fewer independent component parts for a given level of pass band and stop band performance criteria, as compared with a conventional finite impulse response (FIR) filter. The filter is thus ideally suited for implementation with very large scale integration (VLSI) technology, and in a wide variety of electronic devices where high speed digital filtering is required.
