• This paper describes a method of Finite-Impulse Response(FIR)Filter coefficient memory reduction. To satisfy and optimize individual human characteristics of multimedia equipment, many filter coefficient data and loaded memories are needed. Our proposed method for FIR design is to reduce these data and memories by using the Characteristic Function Model(CFM) of human characteristic behavior for stimulus of audio or video signals. CFM consists of the Fundamental Characteristic Function(FCF) and its numerical deviation function(NDF). FCF is modeled from the average data as the human factor. NDF is modeled from the deviation data. This proposal was applied to the experimental development of a sound system and audio circuitry.Especially when there are over 25 FIR coefficient data, it is effective.
