Dual analog window comparator with logic section. Two independent comparators detect when an input signal falls within a user-defined voltage window, with complementary gate outputs and a logic section combining both comparator outputs into AND, OR, XOR, and flip-flop signals.540
Capabilities 2
Analog Logicanalog-logic
Logic section at the bottom combines both comparator gate outputs into AND, OR, XOR, and FF signals, each with a status LED.540
Window Comparatorwindow-comparator
Two independent analog window comparators, each with shift and size parameters (knob and CV), input normalled left-to-right, with gate and NOT gate outputs plus three-color LED status indicators.540

Description
Inputs (6)
L SHIFT CV
cv
—
CV input for the left comparator's shift (window center) parameter. Normalled to the right shift CV input. Accepts negative voltages.540
L SIGNAL IN
mixed
—
Left comparator signal input. Normalled to the right comparator input. Accepts both CV and audio signals.540
L SIZE CV
cv
—
CV input for the left comparator's size (window width) parameter. Normalled to right size CV input. Accepts negative voltages; negative size means output never becomes active.540
R SHIFT CV
cv
—
CV input for the right comparator's shift (window center) parameter. Normalled from left shift CV input.540
R SIGNAL IN
mixed
—
Right comparator signal input. Normalled from left comparator input. Accepts both CV and audio signals.540
R SIZE CV
cv
—
CV input for the right comparator's size (window width) parameter. Normalled from left size CV input.540
Outputs (8)
AND
gate
0V to 5V
Logic AND output: active (+5V) only when both comparators are simultaneously active.540
FF
gate
0V to 5V
Flip-flop output: toggles state on each rising edge of the XOR signal.540
L NOT
gate
0V to 5V
Left comparator complementary (inverted) gate output. Active when input signal is outside the window.540
L OUT
gate
0V to 5V
Left comparator main gate output. Active (+5V) when input signal is inside the window, inactive (0V) otherwise.540
OR
gate
0V to 5V
Logic OR output: active (+5V) when one or both comparators are active.540
R NOT
gate
0V to 5V
Right comparator complementary (inverted) gate output. Active when input signal is outside the window.540
R OUT
gate
0V to 5V
Right comparator main gate output. Active (+5V) when input signal is inside the window, inactive (0V) otherwise.540
XOR
gate
0V to 5V
Logic XOR output: active (+5V) when exactly one comparator is active. Rising edges also toggle the FF output.540
Parameters 4
Name
Type
Range
Behavior
L SHIFT
knob
-5V – 5V
Sets the center position of the left comparator's detection window. Added to L SHIFT CV input to produce the final window center.540
L SIZE
knob
≤10V
Controls the width of the left comparator's detection window, from nearly zero (a few mV) to 10V. Added to L SIZE CV input. Negative size (via CV) means the comparator output never activates.540
R SHIFT
knob
-5V – 5V
Sets the center position of the right comparator's detection window. Added to R SHIFT CV input to produce the final window center.540
R SIZE
knob
≤10V
Controls the width of the right comparator's detection window, from nearly zero (a few mV) to 10V. Added to R SIZE CV input. Negative size (via CV) means the comparator output never activates.540
