[edit] Problems

I think this article is wrong, a 3dB drop in voltage doesn't correspond to half power. A 3dB drop in power is half power. But I'm not changing the article because I don't consider myself an expert in this area. It already looks like someone came along to try to "clarify" the matter and ended up changing what was being said.

Also, a search of the net for "half power point" finds many references regarding filters and none (that I noticed in the first few pages of search results) regarding amplifiers. Maybe that's just how the search results happened to come out - I realize that this term could be used in describing the bandwidth of an amplifier, but it seems to me that it isn't the normal usage. —The preceding unsigned comment was added by 24.128.68.185 (talk) 03:24, 6 April 2007 (UTC).

The article is correct. Decibels are calculated differently for voltage and power. See the article on SNR.152.3.154.115 (talk) 19:39, 5 June 2008 (UTC)
