Ummm...Nigel Goodwin said:It means it's an attenuator, and NOT an amplifier.
Good point(s). I had brain constipation.Nigel Goodwin said:Depends on how it's specified - I was presuming negative gain in dB's - but I take your point, the question wasn't very clear (and still isn't!).

"Only those who dont know wat they are talking about use dBs"

A merry xmas to all our readers, except the lazy students.
Oh hell, merry xmas even to the lazy students.
That's your humble opinion, right?Sceadwian said:Isn't the phase shifting just called an inverting amplifier? Calling that negative gain is a really poor usage of the word.
audioguru said:There is no such thing as a negative amplifier nor negative gain.
The amplifier either has gain or attenuation and its output is either inverted or it is not.
wakiki said:Sorry..it's a typo..what i meant to type is an amplifier with negative gain...Moderators, u can change the title to avoid misunderstanding. I can't edit the thread's title..
Sorry again...Thanks everyone for replying
