  • Notes

  • Rotary attenuator (potentiometer) using switched resistor networks with 2dB steps.

    Traditional potentiometers are implemented with an electrical contact that slides over a resistive layer. This more expensive alternative uses a rotary switch with fixed resistors.

    This offers improved quality of the electrical contact, in comparison with the slider, and is less sensitive to dust and wear.
