Use a Linear Potentiometer to Create a Nonlinear Transfer Function for Audio Volume Control


要約: Linear digital potentiometers (pots) can be used in nonlinear applications, such as adjusting volume control in audio applications. This article discusses how to create a \"pseudologarithmic\" taper digital potentiometer (pot). This is achieved by simply adding a single resistor to the end of the digital pot when configured as a variable resistor.
