ISO 80000-3 describes definitions for quantities and units of space and time. The IEC Standard 60027-3:2002 defines the following quantities. The decibel (dB) is one-tenth of a bel: 1 dB = 0.1 B. The bel (B) is 1⁄2 ln(10) nepers: 1 B = 1⁄2 ln(10) Np. The neper is the change in the level of a root-power quantity when the root-power quantity changes by a factor of e, that is 1 Np = ln(e) = 1, thereby relating all of the units as nondimensional natural log of root-power-quantity r…

If a stage offers a voltage gain of 30, followed with another stage having a voltage gain of 10, the system will have a total voltage gain of 30 x 10 = 300. or, expressed in decibels (2d formula) : 29.5 + 20 = 49.5 dB.

http://www.ilan.schnell-web.net/physics/natural.pdf WebThe natural units of the attenuation constant are Nepers/meter, but we often convert to dB/meter in microwave engineering. To get loss in dB/length, multiply Nepers/length by 8.686. Note that attenuation constant is always a positive number, if it was negative you'd violate the First Law of Thermodymamics (you never get something for nothing!)
