Homework Set 5 Solutions, ECE 25, Fall 2013 The following questions are taken from chapter 5 problems in Mano and Kime, 4th Edition. Some answers are from the website http://writphotec.com//mano4//problem solutions.html and the remainder are taken from a pdf provided to instructors by Pearson. 1. Assume that you are given the S R latch shown in the figure. You are also given the time history of the inputs, as well as the initial state of the latch (the set state). Complete the time history by sketching the Q and Q responses to the inputs. For simplicity, assume there is no time lag in the output response. Keep in mind that changes in state for this kind of latch occur in response to 0 rather than 1. Solution: S R Q Q S R 0 1 0 1 0 1 0 1 Q Q time undefined undefined 1

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
