16-Bit PWM Optoisolated DAC Is PC-Controlled

There was a time when an "honest" (e.g., DNL 1/2 LSB) 16-bit digital-to-analog converter (DAC) was an expensive, premium component. Nowadays they're almost jellybeans ...

PWM-locked-loop seems to work this time (in LTspice, at least)

I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...
