XOR

Discrete resistor-transistor XNOR/XOR/NOT logic gate

directly modelled on RTL digital logic gate designs pioneered in the 1950s used in computing equipment throughout the 50s and 60s.
can be used as audio waveshaper/distortion.
The XNOR/XOR/NOT module can be patched as:
two NOT gates and one 2-input XOR gate,
one NOT gate, one 2-input XOR gate and one 2-input XNOR/XOR gate,
two 2-input XNOR/XOR gates, or,
one NOT gate and one 3-input XNOR/XOR gate.
All analogue circuitry.
slim 4HP footprint.
compact 50mm Depth (with power cable attached).
low power draw: 28mA +12V / 0mA -12V / 0mA +5V.
Works for audio as well as CV.
Fast responding CV inputs allow up to audio rate operation.
The XOR out from gate one is normalized to input 1 on gate two.
The XOR out from gate two is normalized to the single input on gate three (NOT).
signal indicator LEDs on every input and output.
can accept input signal to +10V peak.
