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 matching — Elect. the technique of choosing or adjusting electric circuits and components so that the impedance of the load is equal to the internal impedance of the power source, thereby optimizing the power transfer from source to load. [1925 30] … Useful english dictionary
Matching (disambiguation) — Matching may refer to:* Matching, in graph theory, a set of edges without common vertices * String matching * Impedance matching and Impedance bridging, in electronics, attempting to make the output impedance of a source equal to the input… … Wikipedia
Matching — may refer to: Matching (graph theory), in graph theory, a set of edges without common vertices Matching (statistics), a technique for reducing bias when analyzing data from observational studies String matching, in computer science Matchmaking,… … Wikipedia
Impedance — is a concept associated with the transmission of waves and electrical signals. There are many kinds of waves, and impedance is different in each of them, hence this disambiguation page. However, impedance is also a unifying concept. It is related … 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

matching — The process of making a study group and a comparison group in an epidemiological study comparable with respect to extraneous or confounding factors such as age, sex, weight. impedance m. the force delivered through the mechanical advantag … Medical dictionary
Matching — F/A/V Arranging for the impedances presented by a load to be equal to the internal impedance of the generator. This is essential to avoid loss of power. In microphones, the loss results in poorer signal to noise ratio. Matching is done by means… … Audio and video glossary
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
