This book provides an in-depth look at the Electronics Workbench simulation system, a powerful tool for modeling and analyzing electrical circuits powered by both direct and alternating current. The software's extensive libraries include a wide range of commonly used electronic components, with options to add and create custom libraries. This flexibility allows users to explore the operation of both analog and digital circuits based on modern electronic elements. The book features practical examples designed for self-study, enabling students to develop hands-on skills with laboratory equipment and then simulate laboratory circuits within the EWB environment. It also helps reinforce the skills needed to analyze and calculate electrical circuits effectively. Ideal for full-time, part-time, and accelerated students, this guide is tailored for those studying "Design and Technology of Radio-Electronic Devices" within the field of "Design and Technology of Electronic Systems."
