## Description

Updated with modern coverage, a streamlined presentation, and an excellent CD-ROM, this fifth edition achieves a balance between theory and application.

Author Charles H. Roth, Jr. carefully presents the theory that is necessary for understanding the fundamental concepts of while not overwhelming with the of switching theory.

Divided into 20 easy-to-grasp study units, the covers such fundamental concepts as Boolean algebra, logic gates design, flip-flops, and state machines. By combining flip-flops with networks of logic gates, students will learn to design counters, adders, sequence detectors, and simple digital . After covering the basics, this text presents modern design techniques using programmable logic and the VHDL hardware description language.
