voltage to ground การใช้

• Lines carrying symmetric signals ( those with equal but opposite voltages to ground on each leg ) are often incorrectly referred to as " balanced ", but this is actually differential signaling.
• These conditions can be modeled by exciting a single node inside the DPS and observing the magnitude and phase of the voltages to ground at all points in the LHM . A focusing effect should manifest itself as a  spot distribution of voltage at a predictable location in the LHM.
