[rec.audio] Parametric Equalizer Circuit Needed

jake@northstar58 (Robert W. Fasciano) (07/26/90)

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.
