Question

Quizplus · Accepted Answer

Analog signals are continuously varying signals in which the voltage or other property changes smoothly over time, while digital signals are discrete signals that only have two possible values at set intervals of time. Digital signals do not have a continuous range of values like analog signals, but rather remain at one constant level (0 or 1) and then switch to another constant level.
