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 .
