Digital Circuits

Number systems first

This 65-lecture NPTEL course from IIT Kharagpur begins with what a digital system actually works with: number systems. Several lectures are spent on conversion and representation before any logic is introduced, which gives the rest of the course a firm base.

From algebra to gates

Boolean algebra is developed over a long run of lectures, with the theorems proved and applied rather than just listed. The course then moves to logic gates, so each algebraic rule has a physical circuit to match it.

Who it suits

• Beginners to digital electronics who want the basics taught slowly and in order.
• Students who find Boolean simplification hard and benefit from seeing the theorems worked through repeatedly.
• Learners who plan to continue to combinational and sequential circuits, since this course sets up that material.
