Which statements describe a digital signal? Check all that apply.The signal is made of numbers.The signal degrades over time.The signal is continuous.The signal is not continuous.The signal picks up noise.

A digital signal represents information using distinct values, often encoded as numbers, rather than changing smoothly across a continuous range. So “The signal is made of numbers” and “The signal is not continuous” describe a digital signal. Degradation and noise can affect signals during transmission, but they are not defining features of a digital signal.
