I have never had trouble reading a top post, and in many cases I prefer to. Do you have a brain disease or something? Sad that an engineer can't even comprehend the engineered usefulness of appropriate top posting. Tim -- Deep Friar: a very philosophical monk. Website: http://webpages.charter.net/dawill/tmoranwms
From: Tim Williams on 11 Apr 2010 21:30 Hmm, it would, but in this case the load is resistive, returning to ~zero inbetween pulses (TL494 style waveform). That's not it :) Tim -- Deep Friar: a very philosophical monk.

Q: Why is top-posting such a bad thing? A: Maybe because some people are too annoyed by top-posting. Q: Why do I not get an answer to my question(s)?
