Impedance and admittance.

For multiple reasons, the sweet spot for interconnect and instrumentation impedance is in a relatively narrow range around 50 ohms, and it serves us quite well for signal-integrity purposes, even if the actual single-ended system impedance is somewhat different. PDN impedances, on the other hand, are markedly different.Abstract Impedance and Admittance Control are two dis-tinct implementations of the same control goal.
