Question 1. A lossless transmission line of 50Ω is terminated with load composed resistor in series with a capacitor as shown in figure 1.Voltage Standing Wave Ratio (VSWR) measurement shows value of 3 when operating frequency is 10 MHz, determine the capacitance C.
Question 2. RG-59B/U coaxial lossless cable of 75Ω impedance is used to connect the satellite receiver antenna to the decoder, if the nominal capacitance is 69 pF/m and the diameter of inner conductor is 0.58mm.
What is the inductance per meter.
Obtain the outer conductor diameter.
Question 3. A two wires line is used lead-in wire from the antenna to a television. The cable has characteristic impedance Zo =300 Ω and it is connected directly to the television which has impedance Z_R=150Ω as shown in Figure 1, find the following:
