Targeted for grades 10 through adult, these military-developed curriculum materials consist of a student lesson book with text readings and review exercises designed to prepare electronic personnel for further training in digital techniques. Covered in the five lessons are binary arithmetic (number systems, decimal systems, the mathematical form of notation, number system conversion, mathematical operations, specially coded systems); Boolean algebra (basic functions, signal levels, application of Boolean algebra, Boolean equations, drawing logic diagrams, theorems and truth tables, simplifying Boolean equations); logic gates (diode logic circuits, transistor logic circuits, NOT circuits, EXCLUSIVE OR circuits, operational analysis); logic flip-flops, circuits, and magnetic cores; and logic circuits (counters, registers, adders, decoders, and analog-to-digital encoders). The lessons are designed for student self-study and present basic information concerning computer logic and electronic maintenance. (MN)
