Question

A certain transmission line operating at ω = 10⁶ rad/s has α = 8 dB/m, β = 1 rad/m, and Zo = 60 + j40 Ω, and is 2 m long. If the line is connected to a source of 10∠0° V, Zg = 40 Ω and terminated by a load of 20 + j50 Ω, determine: (a) The input impedance (b) The sending-end current (c) The current at the middle of the line Note: 1 Np = 8.686 dB

Step 1

Given α = 8 dB/m, we need to convert this to Np/m using the conversion factor 1 Np = 8.686 dB. Therefore, α (in Np/m) = 8 dB/m / 8.686 dB/Np = 0.921 Np/m. Show more…
