ENGRD2300: Introduction to Digital Logic Fall 2009 Homework 3 Due Wednesday, Oct 7, at 1:25pm Problem 1. Show how to build the following logic function using one or more 74x138 or 74x139 binary decoders and NAND gates WXYZ (0,1,3,6,11,13,15) Problem 2. Wakerly Exercise 6.38 Problem 3. Draw a block diagram showing how you could construct a 1-bit, 16-1 mux using only 1-bit, 4-1 muxes Problem 4. Using a 1-bit, 8-1 mux with NO additional gates, implement the following 4-input Boolean expression. WXYZ (1,2,5,6,9,11,12,13,15) (It’s easy to do with 1 additional NOT gate, but you have to work a little harder to do it without any NOT gates.) Prob lem 5. Wakerly gives two ways to implement an XOR circuit with many inputs, a daisy-chain structure and a tree structure. Prove that these circuits are equivalent (at least for the 4 input case). 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.
