What is the range of values that a digital signal can take?

• The range of values that a digital signal can take is represented by letters instead of binary digits.

• The range of values that a digital signal can take is infinite and continuous.

• The range of values that a digital signal can take is determined by the frequency of the signal.

• The range of values that a digital signal can take is finite and discrete, typically represented as binary digits (0 and 1) and determined by the number of bits used to represent the signal.
