--- Quote ---In the field of audio and general purpose amplifiers, especially operational amplifiers, the term usually refers to voltage gain,[2] but in radio frequency amplifiers it usually refers to power gain. --- End quote --- Worth noting that when it refers to voltage gain, it's still reported as the equivalent power gain under assumption of equal load impedance. That is, a 10x voltage gain is reported as 20dB because it corresponds to 100x power gain, not as 10dB because it's a 10x gain. Just Wikipedia being a misleading pile fo turd as usual :-- |

Any other use is perversion. --- End quote --- You can reiterate it as many times as you want, but unless you back it up with some actual evidence then I'm just going to ignore it. --- End quote --- You pervert, you! :) |
