6. See-Saw Filter
The See-Saw Filter provides simultaneous cut of one frequency band while boosting
another band. When the adjustment knob is turned clockwise, high frequencies are
boosted and low frequencies are cut. When the adjustment knob is turned count-
clockwise, low frequencies are boosted and high frequencies are cut. The filter has
approximately linear slope over the transition region. Max boost and cut are
approximately 8dB, so significant shaping of the audio spectrum can be achieved.
The See-Saw filter has
a “pivot” frequency that can be sweep over an extremely wide
range of 120 Hz to 26 kHz, in two ranges. The range is selected using a front panel
push button. The See-Saw filter has the same linear slope for each setting. Plots
below show a range of filter responses.
