Try using a fullwave rectifer circuit, most VU and PPM meters use them, this uses both sides of the waveform.
Also, you shouldn't post diagrams as JPG, they are too large and too poor a quality, if you post them as GIF you get 100% quality and a much smaller filesize. JPG is for photographs, and is useless for diagrams.
Sorry about the JPG thing, did not know about that.Thanx for telling me.
About your answer:
An absolute value converter rectifies BOTH sides of the signal, I want to find a way to rectify only ONE side
in relation to which side has the largest peak value..
So, if I have case A then the peak rectifier rectifies only the positive side of the signal, while if I have case B the PR rectifies only the negative side of the signal..
Is there a way to do that??
Maybe with 2 rectifiers and a "switching" way to flip between them?
Hope someone can help,
thanx in advance,
