J.F. Wakerly: Digital Design Principles & Practices, 4th Ed., Prentice Hall, 2005; class and recitation notes.

The OneKey access from Prentice Hall can be helpful to solve the homework problems.

To introduce the basic tools for design with combinational and sequential digital logic and state machines. To learn simple digital circuits in preparation for computer engineering.

A student who successfully fulfills the course requirements will have demonstrated:

1. An ability to define different number systems, binary addition and subtraction, 2’s complement representation and operations with this representation.

2. An ability to understand the different switching algebra theorems and apply them for logic functions.

3. An ability to define the Karnaugh map for a few variables and perform an algorithmic reduction of logic functions.

4. An ability to define the following combinational circuits: buses, encoders/decoders, (de)multiplexers, exclusive-ORs, comparators, arithmetic-logic units; and to be able to build simple applications.

5. An ability to understand the bistable element and the different latches and flip-flops.

6. An ability to derive the state-machine analysis or synthesis and to perform simple projects with a few flip-flops.

7. An ability to understand sequential circuits, like counters and shift registers, and to perform simple projects with them.

At present time the students are not using a computer. If a simple digital logic design program will become available, the laboratory will be redesigned accordingly.

It is a separate course, 14:332:233, associated with this course.

A lot of the homework problems are in fact designing small circuits
