equivalent impedance การใช้

• This is a particularly important transform for finding equivalent impedances.
• In the general case, however, equivalent impedance transforms in addition to series and parallel will be required.
• It is possible to design circuits that are not physically symmetrical but which have equivalent impedances which are symmetrical.
• In case when an appropriate equivalent impedance or admittance inverter loaded at both ports with resonant one-port networks may be matched with the pair of coupled resonators with equal resonant frequencies, the coupling coefficient k is defined by the formula
