nepersm
Nepersm is a term that refers to a unit of measurement for logarithmic quantities, primarily used in telecommunications and information theory. It is analogous to the decibel (dB) in that it expresses a ratio of two quantities on a logarithmic scale. However, nepersm uses the natural logarithm (ln) as its base, whereas decibels use a base of 10. The name "neper" is derived from John Napier, the inventor of logarithms.
The neper (Np) is defined as the natural logarithm of the ratio of two power quantities or
While decibels are more commonly encountered in general engineering and audio applications, nepersm are prevalent in
