Hello Experts, I have a problem understanding ringing concept in lumped and distributed circuits. What I have learned that lumped circuits may or may not ring depending on the Q of the circuit but distributed circuits with terminated load will not have any ringing. where Q for RLC circuit = (L/C)1/2 /R I would like know : 1) Why Q is not important in distributed circuits ? If it?s important then how termination resistor affects Q in distributed circuit ? 2) Is ringing phenomenon ( overshoot & undershoot) in lumped circuit is different than distributed circuit ?
