ECE604 Homework 10 Out: Tuesday, April 13, 2004 (Session 25) Due: Tuesday, April 20 (Session 27) [Students with tape delays: due according to session number] Problem numbers are from the text by Ramo, Whinnery and Van Duzer (3 P rd P edition, 1994). 1. 8.7a 2) 8.7g 3) 8.8d 4) Start with the gaussian function f(t) given by Eq. 8.16(13). Using this in Eq. 8.16(10), show that the envleope broadens with z as given by Eq. 8.16(14). Hint: Use the following Fourier transform identity: ( ) ( ) 1/ 2 2 j t 2 exp t e dt exp / 4 − ω π −Γ = −ω Γ Γ 5) 10.3d Hint: Review section 6.4 and note equivalence between σ and ′′ ωε . 6) 10.4a 7) A simple air-filled transmission line resonantor may be constructed by shorting both ends of a transmission line, as pictured below left, for ideal (lossless) resonator. The ideal resonator supports resonant modes such that m half-wavelengths fit within the resonator, i.e., m L 2 λ = , where m is a positive integer. a) What is the frequency of the m th resonance?

### What students are saying

• 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.
