ECE 329 Homework 11 Due: Tue, Nov 30, 2010, 5PM 1. In the transmission-line circuit shown below all lines are lossless. Calculate the time-average power dissipated at the two loads given that 2Z 01 = Z 02 = 100 Ohm and R L1 = 50 Ohm and R L2 = 50 Ohm. 2. In the transmission-line circuit shown below the voltage at the load is 15 V L Vj = . The operating frequency is 100 MHz. Given that the line is lossless of characteristic impedance of 75 Ohm with wave velocity 8 21 0 × m/s, calculate the following: a. The time-average power dissipated at the load; b. The time-average power delivered by the generator. 3. In the transmission-line circuit shown below all lines are lossless with characteristic impedances Z 01 = 2Z 02 = 100 Ohm. The voltage generator is given to be 10 0 V, Z 100 100 Ohm gg = ∠= + o . If the load impedance is Z5 05 0 O h m L j =+ , calculate the following: a. The time-average power dissipated at the load; b. The voltage and the current at the load. 4. Smith Chart derivation : Consider a complex variable z = r + jx , where r and x are real variables.
