Switching Circuits and Logic Design

A logic design course with a long reach

This 60-lecture NPTEL course from IIT Kharagpur starts with number systems and works toward switching algebra and canonical forms. The early lectures on octal, hexadecimal, signed binary and BCD codes make sure the arithmetic is in place before any logic is built.

Where the course leads

• Error detection and correction, and the logic gates that carry out operations.
• Logic families, showing how gates are implemented in hardware.
• Emerging technologies, in two parts, for readers curious about where switching devices are heading.
• Switching algebra, algebraic manipulation, and the properties of switching functions.
• Canonical representations and functional completeness, which close the listing.

Who it suits

Students in electronics or computer engineering who want the theory behind digital design will get a rigorous treatment. Learners who prefer a shorter, exam-focused path should expect to spend extra time on the algebra lectures.
