Bel (B)
Definition: The bel (symbol: B) is the original logarithmic unit (1 B = 10 dB) expressing power ratios on a base-10 logarithmic scale.
History: Created by Bell Labs for telephone transmission measurements. Named after Alexander Graham Bell. The decibel (0.1 bel) proved more practical for most applications.
Current use: Rarely used directly today, having been largely replaced by decibels. Appears in some historical contexts and theoretical discussions.
Neper (Np)
Definition: The neper (symbol: Np) is a logarithmic ratio unit based on natural logarithms (1 Np = ln(e) ≈ 8.686 dB). It measures field quantities like voltage or current amplitude ratios.
History: Named after John Napier, inventor of logarithms. Used primarily in Europe, especially in fields dealing with wave propagation and transmission lines.
Current use: Mainly in theoretical physics, telecommunications (fiber optics), and electrical engineering where natural logarithms simplify exponential calculations.
