I have a doubt about Decoupling capacitor, I understand that decoupling capacitor is used to decouple power supply to the device, so it acts as a temperery power feeder in case of power shortage. My doubt is how to know at what frequency the power fluctuation would happen? From were we may get this information. Thanks, Sridhar. ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
