Impedance matching definition
In electronics, impedance matching is the practice of designing or adjusting the input impedance or output impedance of an electrical device for a desired value. Often, the desired value is selected to maximize power transfer or minimize signal reflection. For example, impedance matching typically is used … Zobacz więcej Impedance is the opposition by a system to the flow of energy from a source. For constant signals, this impedance can also be constant. For varying signals, it usually changes with frequency. The energy involved can be Zobacz więcej Adjusting the source impedance or the load impedance, in general, is called "impedance matching". There are three ways to improve an impedance mismatch, all of which are called "impedance matching": • Devices … Zobacz więcej In RF connections, impedance matching is desirable, because otherwise reflections may be created at the end of the mismatched transmission line. The reflection may cause frequency-dependent loss. In electrical … Zobacz więcej Whenever a source of power with a fixed output impedance such as an electric signal source, a radio transmitter or a mechanical sound (e.g., a loudspeaker) operates into a load, the maximum possible power is delivered to the load when the impedance of the load ( Zobacz więcej Power factor correction devices are intended to cancel the reactive and nonlinear characteristics of a load at the end of a power line. This causes the load seen by the power line to be purely resistive. For a given true power required by a load this … Zobacz więcej Telephone systems Telephone systems also use matched impedances to minimise echo on long-distance lines. This is related to transmission … Zobacz więcej Acoustics Similar to electrical transmission lines, an impedance matching problem exists when transferring … Zobacz więcej WitrynaImpedance matching in transmission lines is enforced to prevent reflections along an interconnect. Most impedance matching guidelines do not explicitly mention the input …
