Question

Both analog and digital waves can experience noise as they travel. Noise is any unwanted signal that distorts or reshapes the original wave.

Analog and digital waves both need to be amplified after traveling a certain distance. Digital waves are amplified by a device known as a digital repeater. Analog waves are amplified by a device known as an amplifier.

A digital repeater works by reconstructing a new square wave wave from the incoming wave, even if the incoming wave includes noise. An analog amplifier simply amplifies all of the information it receives, including noise. The diagram below illustrates how the resulting waves might appear.



A. -there is no clear advantage to transmitting digital waves over analog waves.

B. -digital waves cannot have noise or other distortions removed from them.

C. -analog waves do not experience as much noise as digital waves.

D. -noise is less of a problem for digital waves than for analog waves.
