CHAPTER 3
Background for Digital Design
3.1 INTRODUCTION
The contents of this chapter are considered all important to the reader’s understanding of
the remainder of this text and, hence, to an understanding of modern digital design methods.
In this chapter the reader will learn mixed logic notation and symbology, Boolean algebra,
and the reading and construction of logic circuits. Besides becoming the industrial standard,
mixed logic notation and symbology, once learned, offers a remarkably simple, direct means
of reading and constructing logic circuits and timing diagrams. Use will be made of the
CMOS logic family to develop this symbology. Other
