GEORGIA INSTITUTE OF TECHNOLOGY SCHOOL of ELECTRICAL and COMPUTER ENGINEERING ECE 2030 Fall 2005 Problem Set #3 SOLUTION Assigned: 19-Sep-05 Due Date: 23-Sep-05 Problem 1 (4 pts): Implement the following using a mixed–logic design methodology. All gates must either have all inputs bubbled or no inputs bubbled. Be sure that all bubbles are paired. Do not assume that the compliment of inputs are available. Do not simplify the expressions. Also determine the number of transistors used by your design. (a) Implement the following expression using 2-input NOR gates and NOT gates. F = A ( B + C ) + DE A B C E D F 24 transistors (b) Implement the following expression using 2-input NOR gates and NOT gates. F ( a, b, c, d, e ) = a ( b + c ) + d e a b c d e F 28 transistors (c) Implement the following expression using 2-input NAND gates and NOT gates.

### 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.
