A cap can be considered as a frequency dependant resistor. High freqs can pass and low freqs can't. Have a look at this picture: http://www.elecdesign.com/Files/29/1478/Figure_01.gif The +5V offset can be considered a very, very low frequency (f->0). On the other hand you can construct a lp filter, by "shortening" the high frequencies through a cap. Then you have to take the signal from before the cap, because the low frequencies stay there. > hehe i'm even more new to this stuff and i really don't understand how > running AC signal through a cap eliminates the DC offset... shouldn't > that eliminate the high frequencies (and thus the oscillation)? > > jure
