How is a Smith chart normalized?

  1. Reassign the reactance axis with resistance values
  2. Reassign the resistance axis with reactance values
  3. Reassign the prime center’s impedance valueRespuesta correcta
  4. Reassign the prime center to the reactance axis

Explicación

Normalizing means dividing every impedance by a chosen reference value — usually the characteristic impedance of the line — so that the chart's center, called prime center, stands for that reference rather than for 1 ohm. Values read off afterwards are multiplied by the same reference to return to ohms.
