Question 4
Find the VSWR in lossless transmission line, if impedance resistance is 100Ω and pure reactance load is (j150)Ω
Question 5
At a frequency of 70 MHz, a lossless transmission line has a characteristic impedance of 500ꭥ and a wavelength of 2m. What’s the value of inductance per meter?
Question 6
Characteristic impedance of a transmission line is 50 Ω. Input impedance of the open circuited line is ZOC = 100 + j150 Ω. When the transmission line is short circuited the value of the input impedance will be
