A coaxial cable is 10 meters long, and is filled with lossless Teflon, having a relative permittivity of 2.1. There is a matched load at the end of the line (this means that there is no reflection at the end, so there is only a signal traveling in the + z direction). At the input of the line, a sawtooth waveform is applied, having a peak voltage of 1.0 [V] and a duration of 1.0 [ns] (the time from the beginning of the waveform until the end). Make a plot (versus time) of what an oscilloscope would read if it were connected to the line at various locations, corresponding to the following values of z: 0.0 [m], 1.0 [m], 5 [m], 10 [m]. Plot out to 50 [ns] 1

1. Matching of a transmission line with a characteristic impedance (Zo) and a load impedance (ZR) can be obtained when (a) ZR=0.5ZO (b) ZR-2Z0 (c) ZR-Zo (d) ZR=0 2. Standing wave ratio (S) for a short circuit load connected to a transmission line is equal to (a) S=0 (b) S=-1 (c) S= Infinity (d) S=1 3. Any transmission line repeats its impedance, voltage, and current characteristics every (Where n-0, 1, 2, 3....etc.) (b) nλ/3 (a) nλ/2 (c) ni/5 (d) nλ/6 4. In smith chart, moving in the clockwise direction means moving a) From load to generator b) From generator to load 5. In Crank diagram, moving in the clockwise direction from the load to the source can be evaluated using the formula a) +j2Bd b)-j3Bx c) -j2Bd d)-j2Bx
