Nepers (NP) Definicija jedinice
The neper (Np) is a logarithmic unit for ratios of measurements of physical field and power quantities, such as gain and loss of electronic signals or sound level. The units name is derived from the name of John Napier, the inventor of logarithms. Just like the decibel (dB) and bel (B), the neper is a unit defined in the international standard ISO 80000. It is not part of the International System of Units (SI), but is accepted for use alongside the SI.
