answer number 3 and 4 Problem 7. Transmission Lines The figure below shows a transmission line with a characteristic impedance Z,-50 Ω, connected to a single frequency generator with an internal impedance R,-50 C (not shown), and terminated in a purely resistive load RL 50 2. At the frequency of the generator, the wavelength of the transmission line is λ = 2 m. At a distance dl-1.25 m away from the load, a shorted stub is connected via a tee....

Note that there is a second valid solution. Problem #2) When an air-filled, slotted-line is terminated with a "short-circuit", voltage minima are measured at positions of 10cm and 25cm on the line. When an unknown load" is connected to the line, the VSWR on the line is 2.4, and voltage minima are detected at 16cm and 31cm. Determine the impedance value of the load in rectangular form), the reflection coefficient of the load (in polar form), and the frequency of...
