| You reverted my Oscilloscope edit http://en.wikipedia.org/search/?title=Oscilloscope&diff=526349171&oldid=526320443 saying that response is flat but limited. You reverted it into stance which says that response reduced to 70.7% serves as the BW limit. That is, response gradually drops to 707% and below. Response drops to 707% and below. You say this is correct and add that it is flat. So, you say that definitely declining response is flat. What a nonsense? I hate fucking reverters. --] (]) 11:01, 15 December 2012 (UTC) | |||
| : Uh, no, that's not what he's saying. The bandwidth of bandwdith-limited systems is almost always quoted in terms of the 3 dB down point (which is equivalent to a voltage drop of 0.707 from nominal). It is perfectly possible for the response of an amplifier to be flat (or practically so) until shortly before that point. As an extreme example, if you assume the rolloff is 3 dB/octave, then if your bandwidth (really the 3dB down point) is quoted at 300 MHz, then attenuation is negligible at 150 MHz (one octave down from 300 MHz) and you can assume a "flat" response below that. In practice the rolloff will be more like 6 or even 12 dB/octave and so you can count on flat response extending correspondingly higher. Bandwidth is nearly always quoted this way because quoting the point at which response drops "just a little bit" from nominal is both vague and impractical. ] (]) 11:14, 17 December 2012 (UTC) | |||

| Have a look at ] at ] It appears to be a hasty revert, possibly without enough study. You have edits that were reverted also and may want to participate or correct some. ] (]) 02:03, 17 December 2012 (UTC) | |||
