ABSTRACT:
An apparatus and method for processing a real input signal representing frames of video information is disclosed. The apparatus and method are embodied in a digital filter comprising means for filtering a real input signal to produce therefrom a real output signal having desired characteristics, the filtering means selecting and acting in accordance with ones of a series of single filter operating parameters selected as a function of real input signal conditions and means for recalling the selected ones of the parameters from a memory, the parameters mathematically derived by simulating a plurality of virtual input signals and filtering the virtual input signals through multiple virtual filters to produce virtual desired output signals.
