Transmission Lines — Telegrapher's Equations, Reflection Coefficient & Input Impedance
Inside this lesson
- Explain why a transmission line must be modeled with distributed parameters rather than lumped elements
- State the telegrapher's equations and identify characteristic impedance Z₀ = √(L'/C')
- Calculate the load reflection coefficient Γ_L for a given Z₀ and Z_L
- Describe qualitatively how input impedance varies with position along a mismatched line
