VARIABLE_BANDPASS_AUDIO_FILTER
This circuit is a variable audio bandpass filter that has a low cutoff variable from about 25 Hz to 700 Hz and a high cutoff variable from 2.5 kHz to over 20 kHz. Rolloff is 12 dB/octave on both high and low ends. R2-a-b and RG-a-b are ganged potentiometers for setting lower and upper cutoff fre-quencies, respectively.
