How does an impedance-matching circuit transform a complex impedance to a resistive impedance?
It introduces negative resistance to cancel the resistive part of impedance
It introduces transconductance to cancel the reactive part of impedance
It cancels the reactive part of the impedance and changes the resistive part to the desired value✓پاسخ درست
Reactive currents are dissipated in matched resistances
توضیح
A matching network is built entirely from reactances. It adds a reactance equal and opposite to the load's reactive component so the two cancel, and it transforms the remaining resistive part up or down to the value the source requires.
