NGSS.MS-PS4-3

Requires LESS power.

• digital

• analog

Noise is

• unwanted, random signals interfering with the intended signal.

• a natural result of waves decreasing in energy and amplitude over long distances.

• caused by radio receivers being unable to interpret waves with low amplitudes.

• intentionally added to radio waves.

Binary digital signals differ from analog signals because

• their amplitude values stay the same no matter the distance.

• they can only have two amplitude values—large and small.
