Question

Question 34 1 pts A multilayer circuit board has dimensions 4 cm by 5 cm by 1 mm. If this board contains power and ground planes that span the entire board, and has dielectric materials with relative permittivity epsilon= 5 between these planes, what are the lowest two (nonzero) resonant frequencies of the board? 1.342 and 2.148 GHz 1.342 and 1.677 GHz 1.677 and 2.148 GHz 3.000 and 3.750 GHz Question 35 1 pts Which of the following statements regarding electrostatic discharge is true? digital circuits are more sensitive to ESD than analog circuits the frequency spectrum of an ESD current is typically in the range 100 MHz<f<500 MHz loop areas on printed circuit boards should be kept as small as possible to minimize coupling from the ESD all of the above
