Final answer:
Network signals that are represented by on-off pulses indicate digital signals.
Step-by-step explanation:
Network signals that are represented by on-off pulses indicate digital signals.
Cell phone conversations, television voice and video images, as well as computer data, are commonly transmitted as digital data, which is converted into a sequence of binary ones and zeros.
In digital circuits, a digital signal switches between two fixed voltage values, such as plus 1 volt and zero volts.
