What is the velocity of a signal propagating along the strip line of Exercise 15.6? Express your answer in m/s and in a percentage of the speed of light. What is the strip line's propagation delay? Is the delay for the Teflon® PCB longer or shorter than the FR4 PCB?
Exercise 15.6
A 12-in. strip line trace is fabricated on an FR4 PCB with a width of 15 mils. It is separated from its ground plane by a spacing of 12 mils. Using the refined estimates of Figures 15.10 and 15.16, calculate the strip line's parasitic capacitance per meter and inductance per meter. What is the strip line's characteristic impedance? Repeat the exercise for the same strip line fabricated using a Teflon® PCB.
Suppose a 1 meter long bar expands 0.5 centimeters when heated. By how much will a 100 meter long bar of the same material expand when similarly heated?
You wish to measure the properties of a high-quality low-pass filter but you only have a normal oscilloscope to observe the Si-like pulse response. How can you deduce the features of the filter from this?
Three series-connected capacitors, C1, C2 and C3, with capacitances 10uF, 15uF and 27uF respectively, are connected in parallel with a 15uF capacitor and a 150V DC source. Calculate: a) Equivalent capacitance of the circuit
Examining frequency to time domain signals, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates t..
