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 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 (input or output) — WikiV The total of the resistance, measured in ohms, that a circuit presents to the flow of alternating current at a given frequency (Columbia University). The characteristics of a system component that determines the type of transmission cable… … Audio and video glossary
impedance — 1. Total opposition to flow. In electricity, when flow is steady, i. is simply the resistance, e.g., the driving pressure per unit flow; when flow is changing, i. also includes the factors that oppose changes in flow. Thus, deviations of i., from … Medical dictionary
