Impedance Bridging
In electronics, especially audio and sound recording, a high impedance bridging, voltage bridging, or simply bridging connection is one in which the load impedance is much larger than the source impedance. In cases where only the load impedance can be varied, maximizing the load impedance serves to both minimize the current drawn by the load and maximize the voltage signal across load. In cases where only the source impedance can be varied, minimizing the source impendance serves to maxmize both the voltage across the load and the current, and therefore maximizing power delivered to the load. The other typical configuration is an impedance matching connection in which the source and load impedances are either equal or complex conjugates. Such a configuration serves to either prevent reflections when transmission lines are involved, or to maximize power delivered to the load given an unchangeable source impedance.

Famous quotes containing the word bridging:
“When its errands are noble and adequate, a steamboat bridging the Atlantic between Old and New England, and arriving at its ports with the punctuality of a planet, is a step of man into harmony with nature.”
—Ralph Waldo Emerson (18031882)
