This is a digitally controllable electronic potentiometer. The heart of the circuit is a 16 channel analog multiplexer ... increases or decreases every time S2 is pressed. u1 AND u2 function as ...

In audio-mixing applications, one frequently required function involves mixing a monaural or single-channel source into a stereo-sound field. Audio engineers refer to a panoramic-potentiometer circuit ...

That spurred him to create the PWMPot which performs a similar function, but with better features than a traditional digital pot. Of course ... high frequencies. The circuit works by driving ...

This all-analog circuit provides three key waveforms simultaneously ... The triangular signal goes to amplifier IC2 via potentiometer P1. It is also routed to the low-pass filter (LPF) or a ...
