Lee Layton, P.E.
Course Outline
The course begins by covering two more fundamental logic gates: the Exclusive OR and the Exclusive NOR gate. From there we cover circuits that can be used to add and subtract numbers. The following chapter covers the basics of Flip-flop circuits including R-S, J-K, T, and D Flip-flops. Counters, registers, and clock circuits are also covered.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Benefit to Attendees
This third course in the series on digital computer logic expands on what we learned in volumes I and II to actually design circuits to add, subtract, and store numbers. The information gained from this course, along with Volumes I and II, will give you a good understanding of how to design a digital logic circuit.
Course Introduction
This is the third course in a series of three courses on digital logic circuits. In Digital Logic Circuits, Volume II, Fundamental Logic Circuits, we studied the four basic logic gates that make up the foundation for digital equipment and looked at the types of logic that are used in equipment to accomplish the desired results.
Digital equipment must be capable of many more operations than those described in volume II of this series. Provisions must be made for accepting information; performing arithmetic or logic operations; and transferring, storing, and outputting information. Timing circuits are included to ensure that all operations occur at the proper time.
In this course we will study the logic circuits used to perform the operations mentioned above. This includes Exclusive OR/NOR Gates, adders, flip-flop circuits, clocks, counters and registers. The first chapter explains the operation of the Exclusive OR gates and the Exclusive NOR gates in detail.
