Digital signals

(i) do not provide a continuous set of values,


(ii) represent values as discrete steps,


(iii) can utilize binary system, and


(iv) can utilize decimal as well as binary systems.


Which of the above statements are true?

Digital signal obviously use the binary signals i.e 0 and 1 only and no other signal other than these. It is also a signal that represents discontinuous values and it cannot utilize decimal values (0 to 9) which are continuous.
