Mini-Quiz: Waveform Noise

by Ron Kurtus (revised 8 March 2006)

Take this Mini-Quiz to check your understanding of the lesson material.



1. What is white noise?

It is real bright and loud noise

It is random background noise

There is no such thing

2. What can cause static on an AM radio station?

Rap music

FM radio stations

Thunderstorms

3. If the S/N ratio is 100, how good is the signal?

It has little noise

It has 100 times as much noise

It is impossible to have a S/N = 100

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
