What is the velocity of a signal propagating along the stippling of Problem 15.7? Express your answer in meters per second and in a percentage of the speed of light. What is the spline's propagation delay? What is its distributed capacitance?
Problem 15.7
An 8-in. strip line trace is fabricated on an FR4 PCB with a width of 24 mils. It is separated from its ground plane by a spacing of 16 mils. Using the refined estimates of Figure 15.10 and Figure 15.16, calculate the strip line's parasitic capacitance per meter and inductance per meter. What is the strip line's characteristic impedance? If we want to lower the characteristic impedance, would we make the layer spacing from trace to ground larger or smaller? If we were constrained to a layer spacing of 16 mils, would we make the trace wider or smaller? If we increased the length of the trace to 16 in., what would happen to the characteristic impedance?
The tray heats up according to ut = c2?u + h(x, y) where h(x, y) = 5(1 - sin(8πy)) and c2 = 10-4. Assume that u = 200 along each edge. Find the steady state temperature distribution of the tray.

Design an amplifier capable of providing the specified gain over a frequency range of 20 Hz to 10Khz under the following conditions. Input source is 2700ohms resistive, and the output load impedance is 32ohms resistive.
The transformer is supplying a load of 325 MVA, with 0.93 power factor lagging at a voltage of 24 kV (line-to-line) on its low-voltage side. It is supplied from a feeder whose impedance is 0.11 + j2.2 ohms connected
The microprocessor then reads the 8-bit data from the dip switch and puts the value in memory starting at location called ‘BUFFER' . This same data is sent to a digital-to-analog converter ( D/A) whose output drives a dc motor.
