Bionic Lester MkII

HM1873mk2 - Dual Switched-Capacitor Filter

BIONIC LESTER MARK II is a dual switched-capacitor filter. Each 2-pole filter section has an attenuverting mixer for its three outputs: lowpass, bandpass, and a selection of either allpass, notch, or highpass. Both sections may be patched in series, or routed (cable-free) in parallel with a balance knob on the mix output.

Because Bionic Lester is a discrete-time system, you may wish to engage the anti-aliasing filter that will enable typical filter behavior for that section. You may also disrupt the high-speed filter clock by logically processing it with the clock from the other filter section.

The resonance control is shared between both sections. The input amplifiers are hot and will distort the filter, with the distortion (and resonance) characteristic depending on the filter’s output mode selection.
