There's probably somebody out there using it as a line encoding. It would be interesting to know.

- gizmo686 3y agoIf you count communication signalling, you do not need to go that exotic. Gigabit Ethernet has 5 levels. At the chip level, it is quite common to see tri-state pins, where the states are: high, low, high-impedidence (e.g, let the rest of the circut set the voltage level). You also sometimes see chips that want a to support a handful of potential values have a pin that can be pulled to multiple intermediate voltages; although you typically hardwire the value with resistors. If you go back far enough, decimal computers were common. The first "real" computer was thr ENIAC which was finished in 1945, and was decimal based. Although even before that, there were more primitive digital computational devices of both the binary and decimal variaty.
