A decade on a graphical logarithmic scale represents multiplication by 10 from the previous value. It is commonly used to represent the frequency response of electronic circuits since depicting frequencies on a linear scale is not practical. For example for an audio amplifier, the frequency band extends from 20 Hz to 20 kHz and representing the entire band using a decade log scale is very convenient. Typically the graph for such a representation would begin at 10 Hz and go upto perhaps 100 kHz as shown below: Value A logarithmic scale is a scale of measurement that gives the logarithm of a physical quantity instead of the quantity itself. ...
A logarithmic scale is a scale of measurement that uses the logarithm of a physical quantity instead of the quantity itself.
Richter magnitude scale for strength of earthquakes and movement in the earth.
A logarithmic scale is also a graphic scale on one or both sides of a graph where a number x is printed at a distance c·10^log(x) from the point marked with the number 1.
