| impedance |
A measurement of the resistance to the flow of AC (which is what audio signals are); impedance is affected by resistance, capacitance, and inductance in a circuit and is also frequency dependent. Impedance is often mistaken for resistance and is also incorrectly thought of as being a measurement of the voltage from a pickup. In practical terms, you want low impedance sources feeding into high impedance loads; this gives maximum accuracy in signal transfer. ...

Impedance is a measure of how hard a signal has to work to get thru a cable, speaker or piece of equipment. Always rated in Ohms, the higher the impedance, the harder for the signal to get thru.

| impedance |
the opposition of an electronic component to the flow of current, measured in ohms. Most commonly thought of as a resistor, however, all devices have impedance associated with them. In transmission lines, it is a measure of the characteristic impedance of a cable, a PCB trace or an interconnect. The impedance of a transmission line (Z O ) is defined as: Z O = ?L/C), where C = capacitance and L = inductance. ...
