How is a Smith chart normalized?
- A.Reassign the reactance axis with resistance values
- B.Reassign the resistance axis with reactance values
- C.Reassign the prime center’s impedance value (correct answer)
- D.Reassign the prime center to the reactance axis
WhyA Smith chart is normalized by reassigning the impedance value at its prime center. A Smith chart is normalized by reassigning the value of impedance at its prime center (the chart's exact middle point), typically set to the system's characteristic impedance (like 50 ohms), so all the plotted values on the chart become ratios relative to that reference rather than absolute ohm values, letting the same chart be reused for any characteristic impedance, answer C. It doesn't work by reassigning the reactance axis with resistance values or vice versa, and it doesn't move the prime center to the reactance axis, those don't describe the actual normalization process.
