Design a stepped-impedance low-pass filter having a cutoff frequency of 3 GHz and a fifth-order 0.5 dB equal-ripple response. Assume R0 = 50, Zl = 15, and Zh = 120. (a) Find the re - quired electrical lengths of the five sections, and use CAD to plot the insertion loss from 0 to 6 GHz. (b) Lay out the microstrip implementation of the filter on an FR4 substrate having εr = 4.2,

A random experiment consists of selecting two balls in succession from an urn containing two black balls and and one white ball. (a) Specify the sample space for this experiment. (b) Suppose that the experiment is modified so that the ball is immediately put back into the urn after the first selection. What is the sample space now? number of repetitions of the experiment in part a? In part b? outcome of the first draw in either of these experiments? (c) What is the relative frequency of the outcome (white, white) in a large (d) Does the outcome of the second draw fron the urn depend in any way on the outcome of the first draw in either of these experiments?
