neper
neper noun: a non-SI unit of the attenuation (or sometimes gain) of field and power quantities such as electronic signals; the natural logarithm of a ratio, with 1 Np (a ratio of 2.718:1) being equivalent to 8.686 dB.
Noun
neper (plural nepers)
- A non-SI unit of the attenuation (or sometimes gain) of field and power quantities such as electronic signals; the natural logarithm of a ratio, with 1 Np (a ratio of 2.718:1) being equivalent to 8.686 dB.
- Values of b, the amplitude attenuation constant, are given for various materials in Table 1.1. Having dimensions of [length]⁻¹, it is usually measured in nepers per centimetre (Np cm⁻¹).1994, T. G. Leighton, The Acoustic Bubble, page 28
- The unit of α is nepers per meter. It can be easily seen that if a line has an attenuation constant of 1 neper/m, a unit amplitude voltage wave will reduce to e⁻¹ over a distance of 1 meter.2006, R. K. Shevgaonkar, Electromagnetic Waves, page 15
