I have created a tutorial to explain decibels. It is located he

http://www.fourier-series.com/rf-concepts/decibels.html

It consists of a flash program that allows user interaction and also
contains a fair amount of embedded audio explanations. The flash
tutorial is about 7M , most of which is the embedded audio.

Actually we don't even have to remember 1.6 to get the numbers in Step
4, we can derive it from previous steps:

Step 2 gave us 9dBm=8mW and Step 3 gave us 7dBm=5mW. So 2dB (9-7) must
be a power ratio of 8/5=1.6

That is a great thought. Thanks for the insight. I'll stick with the
1.6 number in the tutorial though.
