Convert nepers to decibel (amplitude)s
How to convert nepers to decibel (amplitude)s
Convert through a plain ratio: neper → ratio → decibel (amplitude). Logarithmic units cannot be converted by multiplying alone.
Neper: The natural-log counterpart to the decibel. 1 Np ≈ 8.686 dB (amplitude).
Decibel (amplitude): For voltage, pressure and other field quantities. 6 dB is roughly double the amplitude — and the same fourfold change in power.
