At firST gLANce this circuit looks fairly COMplex, but when broken down,can be divided into high pass and low pass filter sections followed by a summing amplifier with a gain of around 20 times. Supply rail voltage is +/- 9V DC. The controls may also be ADjusted for use as a band sTOP (notch) filter or band pass filter.
