An electrical device or circuit whose parts require no power (e.g., there are no transistors or tubes). electromagnetic device that uses one or more coils of wire to isolate or split signals. Also may convert impedanceDefinition:
Also abbreviated as Z. The resistance to AC current flow, measured in ohms (similar to, but not necessarily, the same as DC resistance). and voltageDefinition:
Also called electro-motive Force (EMF). The "charge potential" or pressure of electrons that causes current to flow in a circuit. levels. May be used to eliminate ground loops, reduce Rf interference or crosstalkDefinition:
An undesired audio signal that originates from adjacent wires or adjacent channels..
