[SOLVED] COE328 Lab 1

1 Objectives
• Implementation of simple logic functions using NAND gates
• Design, build and test logic functions using the Karnaugh map method

2 Pre-Lab Preparation
Implementation of the simple logic functions with NAND gates
1. Determine 2 ways to implement an inverter with a 2-input NAND gate.
2. Implement a 3-input NAND gate function using 2-input NAND gates only, draw schematics.
3. Implement a 2-input OR function using 2-input NAND gates only, draw schematics.

4. (A) Implement the function 𝑍 = 𝑓(𝐴, 𝐵) = (𝐴 + 𝐵)𝐴𝐵 using one 2-input OR gate, one 2input AND gate and one 2-input NAND gate.
(B) Implement the same function 𝑍 with only NAND gates.
(C) Make up the truth table for the function. What is the common name of this function? (D) Expand and simplify the Boolean equation to express 𝑍 as a sum of products. Implement the sum of products using only NAND gates. Note: It is possible to do so with 4 NAND gates and no additional inverters.
