Abstract	:	HARDWARE IMPLEMENTATION OF A VARIABLE COEFFICIENT T;INITEIMPULSE RESPONSE FILTER USED IN AUDIO PROCESSINGName: Balster, Eric, J.University of Dayton, 2000Advisor: Dr. F. A. ScarpinoThe graphic equalizer has been a component of audio enhancement for manyyears. A typical equalizer has several active analog filters working in parallel to break upthe input music into various frequency components. The user adjusts these signalcomponent amplitudes, and the adjusted signal components are summed to create theequalized output signal. In this way, the user of the graphic equalizer may dynamicallychange the quality of music listening.However, many problems exist in the areas of analog filtering and traditionalequalizer design. Imprecise analog component values and tolerances give variance incutoff frequencies, which may produce an undesired audio output. Also, electrical noisemay disturb the analog signals and create unwanted tones in the adjusted output signal.Digital filtering, however, is more precise in frequency cutoffs and electricalnoise no longer becomes a problem. Also, only one digital filter needs to be designed to....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
