Document Summary

Lec 8 9-15-16 ch2 problem 2. 32 / problem 2. 33 / Special cases of line ending in short circuit and. From equation 2. 79 in the book can be written as. If the line ends in a short then which makes. We can use the following equations to simplify things. Special case of the lossless line ending in a short circuit a. In general the input impedance at the source of a transmission line has a real part and an imaginary part. At input of the transmission line , thus we have. Note: care must be taken to know on which quadrant lies. In a short circuit the impedance is purely reactive since . 0 the line appears inductive to the source, acting like an equivalent inductor whose impedance equals. We can then find the minimum line length that would give an input impedance equal to an inductor with inductance. We can do the same for a capacitor when.

Excerpt From The Soloist by Steve Lopez

1 I'm on foot in downtown Los Angeles, hustling back to the office with another. deadline looming. That's when I see him. He's dressed in rags on a busy downtown street comer, playing Beethoven on a battered violin that looks like it's been pulled from a dumpster.

2 "That sounded pretty good, " 1 say when he finishes.

3 He jumps back three steps, eyeing me with suspicion. 1 see the name Stevie Wander carved into the face of the violin, along with felt-pen doodles.

4 "Oh, thank you very much," he says, obviously flattered. "Are you serious?"

5 "I'm not a musician," I answer. "But yes. It sounded good to me."

6 He is black, just beyond fifty, with butterscotch eyes that warm to the compliment. He is standing next to a shopping cart heaped over with all his belongings, and yet despite grubby, soiled clothing, there's a rumpled elegance about him. He speaks with a slight regional accent I can't place. Maybe he's from the Midwest or up near the Great? Lakes, and he seems to have been told to always stand up straight, enunciate, carry, himself with pride and respect others.

7 'I'm trying to get back in shape," he says. "But I'm going to get back in there, playing better. I just need to keep practicing."

8 "So you like Stevie Wonder?" 1 ask.

9 "Oh, yes, certainly, 'You Are the Sunshine of My Life.' 'My Cherie Amour.' I guess I shouldn't have written his name on my violin, though."

10 I write a column for the Los Angeles Times. The job is a little like fishing. You go out and drop a line, cast a net. I'm figuring this vagrant violinist is a column. Has to be.

11 "I'm in a hurry at the moment," I tell him, "but I'd like to come back and hear you play again."

12 'Oh, all right," he says, smiling appreciatively but with trepidation. He looks like....
