it would be the same way expansion cards work now; it would have digital control circuitry that can communicate with the analog circuitry.
We already have expansion cards that can do this. Audio cards are an example of an expansion card that convert between digital and analog signals.
Even things like graphics cards, ASICs, or FPGAs; it’s not a different type of signal, but it’s an architecture that isn’t compatible with the rest of the computer because it’s specialized for a certain purpose. So there’s control circuitry that allows it to do that and a driver on the computer that tells it how to.
