2. Logarithmic scale - Wikipedia

   en.wikipedia.org/wiki/Logarithmic_scale

   A logarithmic unit is a unit that can be used to express a quantity (physical or mathematical) on a logarithmic scale, that is, as being proportional to the value of a logarithm function applied to the ratio of the quantity and a reference quantity of the same type. The choice of unit generally indicates the type of quantity and the base of the ...

3. Log–log plot - Wikipedia

   en.wikipedia.org/wiki/Log–log_plot

   A log–log plot of y = x (blue), y = x 2 (green), and y = x 3 (red). Note the logarithmic scale markings on each of the axes, and that the log x and log y axes (where the logarithms are 0) are where x and y themselves are 1. Comparison of linear, concave, and convex functions when plotted using a linear scale (left) or a log scale (right).

4. Semi-log plot - Wikipedia

   en.wikipedia.org/wiki/Semi-log_plot

   The linear–log type of a semi-log graph, defined by a logarithmic scale on the x axis, and a linear scale on the y axis. Plotted lines are: y = 10 x (red), y = x (green), y = log(x) (blue). In science and engineering, a semi-log plot/graph or semi-logarithmic plot/graph has one axis on a logarithmic scale, the other on a linear scale.

   Category for units of measurement or physical quantities in a logarithmic scale. Subcategories. This category has the following 2 subcategories, out of 2 total. E.

6. Logarithm - Wikipedia

   en.wikipedia.org/wiki/Logarithm

   Scientific quantities are often expressed as logarithms of other quantities, using a logarithmic scale. For example, the decibel is a unit of measurement associated with logarithmic-scale quantities. It is based on the common logarithm of ratios—10 times the common logarithm of a power ratio or 20 times the common logarithm of a voltage ratio.

7. Decade (log scale) - Wikipedia

   en.wikipedia.org/wiki/Decade_(log_scale)

   For example, an audio amplifier will usually have a frequency band ranging 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 1 Hz (10 0 ) and go up to perhaps 100 kHz (10 5 ), to comfortably include the full audio band in a standard ...
