Extra exam question E9E07
Subelement E9, ANTENNAS AND TRANSMISSION LINES· Group E9E
What parameter describes the interaction of a load and transmission line?
- A.Characteristic impedance
- B.Reflection coefficient (correct answer)
- C.Velocity factor
- D.Dielectric constant
WhyReflection coefficient is the parameter that describes the interaction of a load and a transmission line. Reflection coefficient is the parameter that describes the interaction between a load and a transmission line, quantifying how much of an incident wave reflects back toward the source because the load's impedance doesn't match the line's characteristic impedance, answer B. Characteristic impedance and velocity factor describe properties of the transmission line itself, and dielectric constant describes a material property, none of them specifically characterizes the load-to-line interaction the way reflection coefficient does.
