As I believe the term "digital" is usually meant, it implies a
two-state (on/off) storage representation. It's not just that the
signal amplitude is quantized, but that the quantization uses a
power-of-two representation and storage system of some sort.

It means discrete states, but the base does not have to be two.

Many of the early computers were decimal based, and not
necessarily BCD.

The Fortran standard still allows for any base greater
than one to be used for representing values.
