Why might an analog television need an antennae?

• to conduct electricity to the tv

• to increase color attributes to the screen

• to increase the volume of the sound

• to intercept the station's signals through a conductor

An advantage a digital wave has over an analog wave is

• It can be perfectly duplicated.

• It is cheaper to make.

• It is longer and conserves energy.

• It doesn't cause cancer.
