- > The term "Discrete" uses to describe a signal with two modes.
- Wrong. Discrete means it can only take some values , not all values.
- I suspect by 'modes' you mean # of possible outputs. If we have a system which outputs only have 1 possible output then what would be the point of that system?
- Sure we can make a system which has 3 possible outputs , I think this kind of system already exists in [spintronics](https://en.wikipedia.org/wiki/Spintronics)
where not only do we measure the charge state but also the spin state.So we can have 3 different states[no charge state,charge state/spin up,charge state/spin down]- Hope this helps.
