| 11. | A frequent format used for impedance matching in waveguide is the stepped impedance filter.
|
| 12. | Microwave ovens I believe use changes in the cavity impedance matching to determine heating profiles.
|
| 13. | The ability of the tympanum and stapes to effectively transmit vibrations is called impedance matching.
|
| 14. | The one at the right is not a balun, as it provides only impedance matching.
|
| 15. | The result of this is that even ballpark impedance matching to an amplifier is impossible.
|
| 16. | To learn more, I suggest you read impedance matching.
|
| 17. | Technically it is a matter of impedance matching between air motion and the individual fibres.
|
| 18. | Transmission line cables require impedance matching to carry electromagnetic signals with minimal reflections and power losses.
|
| 19. | Typical circuit blocks implemented by transmission lines include directions couplers and power splitters, and impedance matching.
|
| 20. | Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching.
