Sorry, I did. It fell off when I fixed the shifts that apeared when copying. Fixed it again. I seem to have forgotten what the bar meant. I knew it when I needed it for a test, but I lost it. Is it the arithmic mean? The arithmic mean is a way of averaging, if wikipedia (http://en.wikipedia.org/wiki/Arithmetic_mean) is correct. The average of a sine (if N cycles are taken) is 0. If the arithmic mean of a sine is plotted over a time period the result would be the exact same sine. The result of this would be that RMS is a useless value. It is not, and therefore my reasoning must be flawed somewhere. Does anyone have the time, knowledge and will to take the quest of finding this flaw? I seem to be unable to.
While the average of sin x over an an entire cycle is zero, it's not for sin^2 x, which of course never goes negative. -- Use OpenOffice.org <http://www.openoffice.org> -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
