There is a interesting comparision that I have found between decoding resistor color codes and decoding Decibel values:
Resistor Color Codes:
On resistors, the first two color bands describe a particular value, without a decimal point description
i.e. the digits "39" can be 3.9 or 39 or 390
{on a side note, I taught fluent color-code in 18 minutes, in the classroom for over 30yrs}
Decibel Coding (or Decoding):
The "Basic Decibel Value" is the Value that expresses or converts Logarithymically to a "Factor" for gain or loss.
The number to the left of that Basic Decibel Value is "The Multiplier", as a power of the Base 10^{x}.
With "1" simply being a Multiplier of 10 times the Factor,
or with "2" simply being a Multplier of 100 times the Factor,
or with "3" simply being a Multiplier of 1,000 times the Factor .
Actually, the entire number expressed is actually a Logarithic Value as an exponent of the Base 10^{x},
but considering that there is a "hidden decimal point" involved.
i.e. 24Db would be considered as 10^{2.4} (note the decimal point between the 2.4)
How to determine Decibel Values and Examples: (DB_Tables pdf, or DB_Tables.html)
(no points discounted for speiling errers)
