Unformatted text preview: Name: Student Number: ELEC3909 Quiz 5 June 12, 2003 1. It’s the seventh game of the 2009 Stanley Cup final and Vancouver is playing Ottawa. Your TV is broken, but you manage to find a dusty old black and white TV in the basement. This old TV has an input impedance of 300 Q. You can’t find an antenna for the TV, so you have to connect it to the 75 0 cable TV E system. The cable signal is very weak, so you decide to match the TV to 75 0 using the network built from 1“ lengths of 75 (1 cable as suggested below. The cable has a dielectric with eT = 2.25. The game is on channel 2 at 50 MHz. Show your work on the admittance Smith chart attached. 0 TV ‘ W 30:19.5 >3 arm n sirw‘i? a) What is the normalized conductance of the TV input? Plot this on the Smith chart.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
