In Reply to: Timing in wire????? posted by real_jj on June 6, 2006 at 13:22:28:
Nah, fughetttaabout lightspeed.What's the delay for a distributed R/C/L lowpass?
I do first order lumped, get 1.6 uSec, do second order, get bout 6 uSec. Both go flat about 1% of ω. Haven't run a pure distributed analysis to see how the distributed L affects delay, but it certainly doesn't seem to go to zero at DC. A physics thing..
Curiously, for non matched transmission lines, the energy storage within the wire gets up to 5 to 10% of the energy of a 10Khz sine. another oddity.
Cheers, John
