Input impedance — The input impedance, load impedance, or external impedance of a circuit or electronic device is the Thévenin equivalent impedance looking into its input.In audio systemsGenerally in audio and hi fi, the input impedance of components is several… … Wikipedia
Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… … Wikipedia
Impedance bridging — In electronics, especially audio and sound recording, a high impedance bridging, voltage bridging, or simply bridging connection is one which maximizes transfer of a voltage signal to the load. The other typical configuration is an impedance… … Wikipedia
High impedance — In electronics, high impedance(also known as hi Z, tri stated, or floating) is the state of an output terminal which is not currently driven by the circuit. In digital circuits, it means that the signal is neither driven to a logical high nor low … Wikipedia

High-Z looping input — A&V A high impedance input circuit which also includes an output to enable routing the signal to another piece of equipment … Audio and video glossary
Nominal impedance — in electrical engineering and audio engineering refers to the approximate designed impedance of an electrical circuit or device. The term is applied in a number of different fields, most often being encountered in respect of: The nominal value of … Wikipedia
Acoustic impedance — The acoustic impedance Z (or sound impedance) is a frequency f dependent parameter and is very useful, for example, for describing the behaviour of musical wind instruments. Mathematically, it is the sound pressure p divided by the particle… … Wikipedia
Dual impedance — and dual network are terms used in electronic network analysis. The dual of an impedance is its algebraic inverse . Note that and are the duals of each other, that is, they are reciprocal. For this reason the dual impedance is also called the… … Wikipedia
Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… … Wikipedia
Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… … Wikipedia
