The course “Digital Techniques” provides an in-depth understanding of the fundamental principles of digital electronics that form the foundation of all modern computing and communication systems. It is designed to help learners develop a clear conceptual and practical understanding of how digital systems represent, process, and store information using logical and electronic means.
The course begins by exploring how real-world numerical data and signals are represented in digital form through various number systems and coding techniques. Students will understand how digital circuits perform arithmetic operations and logical decision-making using binary logic.
Building on this foundation, the course delves into the essential elements of digital design — logic gates and Boolean algebra — which serve as the building blocks for all digital systems. Learners will acquire the skills to simplify logical expressions, optimize circuits, and implement digital functions efficiently.
The course further emphasizes the analysis and design of both combinational and sequential logic systems. Students will learn how to design circuits that perform specific logical and arithmetic operations, as well as systems that can store and process data based on timing and control signals. Topics such as flip-flops, registers, and counters are discussed in detail to help learners understand how memory and control are integrated into digital systems.
In addition, the course introduces the fundamental concepts of semiconductor memories and data storage. Learners will gain insight into the classification, structure, and operation of various memory types and their role in digital computing systems. along with that the course gives some application examples utilizing the digital techniques.
