E7C04 : How does an impedance-matching circuit transform a complex impedance to a resistive impedance?
A
It introduces negative resistance to cancel the resistive part of impedance
B
It introduces transconductance to cancel the reactive part of impedance
C
It cancels the reactive part of the impedance and changes the resistive part to the desired value
D
Reactive currents are dissipated in matched resistances
Correct Answer: It cancels the reactive part of the impedance and changes the resistive part to the desired value
