ECE 329 Homework 11 Due: Tuesday April 12, 2011, 5PM 1. Telegraphers equations govern the voltage and on-going (T.L.) systems. a) If ?V ?I ?I ?V =L and ? =C ?z ?t ?z ?t waves V (z, t) and I(z, t) that pervade ? on lossless transmission line V (z, t) = ?4 cos(?t ? ?z) is a solution to the telegraphers equations, mark the associated current waveform I(z, t) ? (a positive number) in terms of constants b) Determine the wavenumber L and C. paint a picture: First use whizz of the telegraphers equations to even up phers equation to determine in step 2 to match the 2. For a I(z, t). therefore use the some other telegraV (z, t) from I(z, t) found in the rst step. By requiring V (z, t) found original V (z, t) you should be capable to identify ? . v = 5 × 107 m/s. Z0 = 50 ? = c 3 coaxial cable, nd the inductance and capacitance per unit of measurement aloofness if 3. Consider a T.L. with characteristic impedance v= ?1 LC = 1×108 m/s. A voltage descent Zo = 75 ?, length l = 100 m, and propagation speeding f (t) with an internal subway Rg = Zo is connected to one suppress of the T.L. (at 1 z = 0) and the other end (z = l) is terminated by a load justification RL = 2 Zo . a) Construct a bounce diagram to determine the voltage, on the line for V (z, t), and current, I(z, t), variations 0If you want to get a full essay, order it on our website: OrderEssay.net
