20 dB is always the same, actually. If you multiply voltage (and thus current as well) by 10:1 (20 db) the power is multiplied by 100:1 (also 20 dB)

- rcxdude 1y agoThat's the point that's confusing. Especially in contexts where it's not obvious whether it's power-like or amplitude-like. It should be 40dB of power gain or 20dB of amplitude gain, with the context made explicit.
- mikewarot 1y agoI don't see how it's confusing. Thanks to the scaling of voltage dB, you never have to worry, 10 dB of voltage gain is the same as 10 dB of power gain.
