Tocci and Widmer use a block diagram approach to basic logic operations, to enable students to have a firm understanding of logic principles before they study the electrical characteristics of the logic ICs. For each new device or circuit, the authors describe the principle of the operation, give thorough examples, and then show its actual application. | Tenth Edition Digital Systems Principles and Applications RONALD J.TOCCI NEAL s.WIDMER GREGORY L.

INTRODUCTION In today s world the term digital has become part of our everyday vocabulary because of the dramatic way that digital circuits and digital techniques have become so W idely used in almost all areas of life computers automation robots medical science and technology transportation telecommunications entertainment space exploration and on and on. You are about to begin an exciting educational journey in which you will discover the funda mental principles concepts and operations that are common to all digital systems from the simplest on off switch to the most complex computer. If this book is successful you should gain a deep understanding of how all digital systems work and you should be able to apply this understanding to the analysis and troubleshooting of any digital system. We start by introducing some underlying concepts that are a vital part of digital technology these .
