Fasciano) Followup-To: sci.electronics Organization: Project NORTHSTAR, Dartmouth College Lines: 7 References: I'm looking for a circuit design for an audio PARAMETRIC EQUALIZER. The idea behind the circuit is that it is able to amplify or attenuate a narrow, variable frequency. There are two control knobs, one controls the center frequency, the other determines the amount of gain or attenuation. Any references or infomation would be helpful.
