Что (кто) такое impedance matching - определение


Impedance matching         
  • alt=Schematic diagram of coaxial cable
  • page=223}}</ref>
  • Basic schematic for matching R<sub>1</sub> to R<sub>2</sub> with an L pad.  R<sub>1</sub> > R<sub>2</sub>, however, either R<sub>1</sub> or R<sub>2</sub> may be the source and the other the load. One of X<sub>1</sub> or X<sub>2</sub> must be an inductor and the other must be a capacitor.
  • alt=Schematic diagram of amplifier and speaker, with two tubes and an impedance-matching transformer
PRACTICE MATCHING LOADS TO POWER SOURCES IN ENGINEERING
Impedance match; Impedance mismatch; Matching network; Mismatched impedance; Mismatched impedances; Impedence matching; Line impedance; Impedance-matched
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.
Electrical impedance         
  • complex impedance plane]]
  • load]] <math>Z</math>, driving a current <math>I</math>
  • Generalized impedances in a circuit can be drawn with the same symbol as a resistor (US ANSI or DIN Euro) or with a labeled box.
  • The phase angles in the equations for the impedance of capacitors and inductors indicate that the voltage across a capacitor ''lags'' the current through it by a phase of <math>\pi/2</math>, while the voltage across an inductor ''leads'' the current through it by <math>\pi/2</math>. The identical voltage and current amplitudes indicate that the magnitude of the impedance is equal to one.
QUOTIENT OF THE VOLTAGE PHASOR AND THE ELECTRIC CURRENT PHASOR
Impedances; Electric impedance; Complex electric impedance; Electric effective resistance; Complex impedance; Conductor impedance; Electric complex impedance; Impedance of different devices (derivations); Deriving capacitor impedance; Complex Impedance; Phasor impedance; Electrical impedence; Capacitor impedance; Inductor impedance; Resistor impedance; Complex impedence; Impedance (electrical); Inductive impedance
In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.Slurzberg; Osterheld (1950).
Bracket matching         
A SYNTAX HIGHLIGHTING FEATURE OF CERTAIN TEXT EDITORS AND INTEGRATED DEVELOPMENT ENVIRONMENTS THAT HIGHLIGHTS MATCHING PAIRS OF BRACKETS.
Braces matching; Brace matching
Bracket matching, also known as brace matching or parentheses matching, is a syntax highlighting feature of certain text editors and integrated development environments that highlights matching sets of brackets (square brackets, curly brackets, or parentheses) in languages such as Java, JavaScript, and C++ that use them. The purpose is to help the programmer navigate through the code and also spot any improper matching, which would cause the program to not compile or malfunction.
