Coefficients/Potentiometers

Coefficients and assigned potentiometers are on different places on the board and put here together only for visualization.

Coefficients are quantitative parameters that enter analog computations in a multiplicative fashion. Using potentiometers, coefficients can be set to any value between 0 and +1. Their output is given by output = coefficient * input. The Analog Thing features eight coefficient potentiometers, allowing the use of eight coefficients in an analog computation.

How to use a coefficient

Say you want to compute +0.5 = 0.5 * (+1). Then follow these steps:

1. First, decide which coefficient to use. They are numbered. Say you want to use number 1.
2. Put a plug into the input for coefficient 1. Connect it to some +1 source.
3. Put a plug into the output of coefficient 1 and use it wherever you want.
4. Tune the potentiometer to the middle/center, around 0.5

How to fine-tune a potentiometer

THAT offers the COEFF mode for fine-tuning coefficients. In this mode, the Voltmeter displays the exact value of the meter position of the potentiometer chosen in the coefficient plug (highlighted in red).
