Summary

This circuit consists of multiple rotary potentiometers connected to two 16-channel analog multiplexers. The potentiometers are used to provide variable resistance, which is then read by the multiplexers. The multiplexers are configured to select one of the potentiometer signals at a time and output it to a common signal line. This setup allows for the reading of multiple potentiometer values using a single analog input on a microcontroller or other analog-to-digital conversion system.
