[ EDIT -- The previous paragraph doesn't make sense. In any context where it isn't clear whether it is voltage or power gain that is being referred to, the statement "Gain = 20 dB" is ambiguous. It could mean either "V2/V1 = 10 , P2/P1 = 100" or "V2/V1 = 100 , P2/P1 = 10000". If what was meant was "unless stated otherwise, it's assumed that gain refers to power rather than voltage", then that's what should have been said. Edit to Edit - The original statement is correct because a 10x voltage increase is equivalent to a 100x power increase, and both a 10x voltage increase and a 100x power increase correspond to a gain of 20 dB. Therefore, it is uneccessary to specify if the gain refers to a power increase or a voltage increase as the two are related. ]
[edit] Split
I have split up gain so that now this aritcle only discussed the electornics side of things. See Gain (disambiguation) for where the other info ended up.--Commander Keane 20:51, 9 December 2005 (UTC)
- Split looks good as is. The paragraph on antenna gain is probably OK here, especially since the decibel equations above it are essentially correct for antenna gain calculation as well. --ssd 12:54, 24 January 2006 (UTC)
- I agree that the antenna gain deserves a place in here. Anyone looking for more information on Antenna Gain in particular can go to the link, those who just want a general overview of gains regarding electronics can only "gain" (heh heh!) from seeing that it can be applied to EM design also. --Diom1982

- I think antenna gain should be kept with antennas. Electronic gain requires energy input from a power supply. Antennas dont provided gain in this sense, they just capture more energy than an isotropic reciever would.--Light current 17:44, 9 February 2006 (UTC)

- I have moved antenna gain stuff to antenna now.--Light current 17:51, 9 February 2006 (UTC)

[edit] Huah?
This article sucks. It has no preamble to describe what gain is. Maybe you electricians understand it, but it's useless to others. —The preceding unsigned comment was added by 129.97.234.72 (talk) 19:44, 6 December 2006 (UTC).
