[NSRCA-discussion] electric interference question

[Ed Alt]

Yep.  In fact, if you could generate a perfectly square wave edge, it means that you are looking at an infinite number of sine wave frequency harmonics of the fundamental freq all added together.  Just can't get away from that analog stuff.  Very disturbing!

  Digital signals are still subject to rise and fall time degradation. Analog stuff within any segment of the signal. Always was. And still subject to loss with distance. 

  Any electrical component is subject to the Chemistry that created it. Chemistry was, is and always will be analog. Drives Electrical Engineers nuts. (VBG)

    BTW - Any problem that can be solved with Ferrite beads is in fact Black Magic. It's right up there with coiling the scope probe lead in the opposite direction to get a cleaner signal. Who says this is a digital world? <LOL>
