Question
Download Solution PDFA transmission line has a characteristic impedance of 500 Ω. It has been terminated in a 200 Ω load. If the load is dissipating a continuous power of 100 W, its reflection coefficient is
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
The reflection coefficient gives the percentage of incident voltage reflected from the load.
Mathematically, this is defined as:
\(Γ = |\frac{{\left( {{Z_L} - {Z_o}} \right)}}{{({Z_L} + {Z_o})}}|\)
Γ = Reflection coefficient
Z L = Load Impedance
Zo = Characteristic Impedance.
Application:
With Zo = 500 Ω and ZL = 200 Ω, the characteristic impedance is:
\(Γ = |\frac{{\left( {{200} - {500}} \right)}}{{({200} + {500})}}|\)
\(\Gamma =\frac{3}{7}\)
