E7C04:

How does an impedance-matching circuit transform a complex impedance to a resistive impedance?

  1. It introduces negative resistance to cancel the resistive part of impedance
  2. It introduces transconductance to cancel the reactive part of impedance
  3. It cancels the reactive part of the impedance and changes the resistive part to a desired value
  4. Reactive currents are dissipated in matched resistances
