Course Description

Digital electronics is a field of computer science engineering and especially electronics concerned with the study of analog and digital signals and the devices to produce them, specially built for Polytechnic Computer Science Engineering diploma Sem-3 CSE and Degree standard students. It involves a theoretical foundation of digital electronics. Many of the modern facilities like smartphones, AV systems, computers, kitchen appliances, washing machines etc. are based on digital electronics.
