A digital signal is a signal that represents information as a series of discrete binary values. Digital signals are used in all modern electronic applications, including communication and network devices. When plotted in a voltage-time graph, the signal is discrete, and ranges from 0 V to VCC (usually 1.8V, 3.3 V, or 5V).
