= Example 6.8. A dc source of 120 V with negligible resistance is connected through a switch S to a lossless transmission line having Zc 30. The line is terminated in a resistance of 90. If the switch closes at t = 0, plot R versus time until t = 5T, where T is the time for a voltage wave to travel the length of the line. The circuit is shown in Fig. 6.14(a). Solution. When switch S is closed, the incident wave of voltage starts to travel along the line and is expressed as v = 120U(vt - x) Why did he use that formula if the formula shown 6.78 is a different? If we express a forward traveling wave, also called an incident wave, as v=f₁(x-vt) (6.78)

Q8 - You wish to end up with a 2um width metal line (measured at the top of the metal lead cross section). A) You are using an isotropic wet etch process on a 1um thick metal layer. What linewidth should the protective photoresist line be to get these results? Sketch the resulting structure before photoresist strip. B) now you are using a completely anisotropic etch, what is the requisite linewidth of the photoresist to achieve the same end goal? Sketch the resulting structure before the stripping of the photoresist.
