CO OZNACZA SŁOWO NEPER
Neper
Neper jest logarytmiczną jednostką stosowaną do pomiarów pola fizycznego i mocy, takich jak zysk i utrata sygnałów elektronicznych. Nazwa jednostki pochodzi od imienia Johna Napiera, twórcy logarytmów. Podobnie jak w przypadku decibelu i bel, neper jest jednostką Międzynarodowego Systemu Ilości, ale nie jest częścią Międzynarodowego Systemu Jednostek, ale jest dopuszczony do użycia obok SI.
