Overview

In this module we will examine combinations of basic gate logic components to provide the foundation for designing and analyzing digital circuits. We will see that Boolean Algebra provides a useful construct for representing combinations of basic logic gates. Boolean expressions (or functions) will be represented in tabular form called truth tables. We will see equivalent implementations of the Boolean expression permitting one to simplify the Boolean expressions to achieve the most efficient circuit design. DeMorgan’s Theorem and Karnaugh Maps or K-Maps will be covered. The module concludes with an introduction to encoding and decoding using the 7 segment display as a representative translation of binary date to a decimal display for human interpretation.

Objectives

By the end of this module, you will be able to:

Create basic logic gate configurations that are equivalent to a Boolean expression and vice versa.
Manipulate Boolean expressions using basic Boolean operational properties to simplify the expression.
Apply DeMorgan’s Theorem to transform Boolean expressions.
Construct Boolean expressions involving sums of products or products of sum from a truth table.
Simplify a Boolean expression using Karnaugh Maps.
Demonstrate using logic gate circuits to control a seven segment display.

Learning Guide

Cell description

Go to the module content and begin by downloading and reviewing the printed slide presentations. Then view the video presentation for a slide set. You can stop the presentation or replay sections if necessary to gain a good understanding of the material. Make any notes on your printed copy of the slides. After completing a slide presentation go to the self-test section and complete the test. This will reinforce the things you have learned and help you with any misunderstandings. Repeat this process for the next slide presentation set until you have viewed all of slides in the module content. Prepare and participate in the online discussion. The discussion questions can be found in the Discussion section below. Complete this module by submitting the module assignment as a PDF document. Please post any questions to the Q & A section of the Discussion Board.
