Compare to the --at lest now, pretty obscure-- "Neper", which I've never seen used in practice except that I own a very old analog meter with a scale in Np... https://en.wikipedia.org/wiki/Neper The Np seems to have be used for amplitudes (rather than power), and value/ref = e^Np. And 0.01 Np ~ 1.01 (+1%) which is probably less useful than it seems at first glance. |
