That is of course not true. dB without reference is perfectly fine to use for gain and attenuation. dBm or any of the variants would be flat out wrong.

- mitthrowaway2 1y agoEven then, you'll get different results if it's 10 dB of voltage gain or 10 dB of power gain. You need to know what the actual units are.
- mcnamaratw 1y agoNo, dB are always power gain.
- davrosthedalek 1y agoExactly, and that's why a voltage gain of factor 10 is 20dB, because it's a power gain of factor 100.
