INSTRUCTION: Answer the following set of problems in a short bond paper. Write (Handwritten) clearly your solution and box your final answer(s) 1. A transmission line has the following primary constants per loop kilometre run: R=12 ohms, L=3mH, G=4u5 and C =0.02pF. Determine the characteristic impedance of the line when the frequency is 750Hz. 2. A transmission line having negligible losses has primary constants: inductance L=1.0 mH/loop km and capacitance C =0.20 uF/km. Determine, at an operating frequency of 50KHz, (a) the characteristic impedance, (b) the propagation coefficient, (c) the attenuateon and phase-shift coefficients, (d) the wavelength on the line 3. A coaxial line has a characteristic impedance of 100 ohms and is terminated in a 400 ohms resistive load. The voltage measured across the termination is 15V. The cable is assumed to have negligible losses. Calculate for the line the values of (=) the reflection coefficient, (b) the incident current, (c) the incident voltage, (d) the reflected current and (e) the reflected voltage
