🚩 Course Overview and Objectives

This course is an introductory training program designed for engineers who are new to electronic circuits or just beginning digital design fundamentals. It provides a systematic understanding of the operating principles of various digital blocks such as timers, oscillators, counters, decoders, and LED drive circuits, as well as the overall system architecture flow.

Based on 35 years of practical experience from Professor Cho Sung-jae of Shinhan University,
this course focuses on practice-oriented learning of core digital circuit concepts that junior engineers must understand: timer-based LED control, frequency generation principles for musical note generation, the operating structure of octal Up-Down Counters, combination methods of astable oscillators and counter selection circuits, and digital system implementation leading to electronic dice. All essential fundamentals are organized in a hands-on manner.
