Both analog and digital waves can experience noise as they travel. Noise is any unwanted signal that distorts or reshapes the original wave. The diagram below illustrates how the resulting waves might appear. The example above suggests that...

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

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

• analog waves do not experience as much noise as digital waves.

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

It is far more difficult to make a perfect copy of an analog wave because...

• the exact value of any one piece of information is not clearly defined.

• most analog waves have wavelengths that are too long to reproduce in copies.

• analog waves travel at speeds too great for modern technologies to use.

• each individual piece of information is either a zero, a one, or a two.

How is the information from the audio wave stored after it is processed by the analog-to-digital converter?

• It is stored as a table of ones and twos because it was converted to a radio wave.

• It is stored as images because it was converted to mathematical equations.

• It is stored as a series of ones and zeros because it was converted to binary data.

• It is stored as graphs because it was converted to base ten data.
