| 21. | Variable capacitors are often used in reactance, e . g . for impedance matching in antenna tuners.
|
| 22. | Impedance matching is neither necessary nor desirable.
|
| 23. | In terms of the reactance half-plane to the Smith chart used for impedance matching of transmission lines.
|
| 24. | Most shortwave broadcasters have continued to use high-impedance feeds even before the advent of automatic impedance matching.
|
| 25. | Owned by Dunlop, it produces what is known as " impedance matching of club and ball ."
|
| 26. | Its use as a connector for composite video signals is extremely common, but provides poor impedance matching.
|
| 27. | The transformation ratio is the ratio of the input and output impedances of the impedance matching network.
|
| 28. | Impedance matching is not always necessary.
|
| 29. | The Impedance Matching Room has a matching transformer to perform impedance matching between the transmitter and the antenna.
|
| 30. | Impedance matching, does it really matter?
