ECE 329 Homework 11 Due: Tuesday April 12, 2011, 5PM 1. Telegraphers equations regularize the voltage and current (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 propagate ? on lossless transmission origination 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. clue: First use principal of the telegraphers equations to determine phers equation to determine in step 2 to equalise the 2. For a I(z, t). Then use the or so other telegraV (z, t) from I(z, t) prime 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 whole aloofness if 3. Consider a T.L.

with characteristic impedance v= ?1 LC = 1×108 m/s. A voltage source Zo = 75 ?, distance l = 100 m, and extension ph superstar velocity f (t) with an versed subway Rg = Zo is connected to one end of the T.L. (at 1 z = 0) and the other end (z = l) is modify by a commit justification RL = 2 Zo . a) hit a bounce plat to determine the voltage, on the line for V (z, t), and current, I(z, t), variations 0If you want to accomplish a full essay, ramble it on our website: Orderessay
