Switching Circuits and Logic Design

Indian Institute of Technology, Kharagpur and NPTEL via Swayam

This course may be unavailable.


This course will discuss the basic background of switching circuits, and discuss techniques for mapping the theory to actual hardware circuits. Synthesis and minimization techniques of combinational and sequential circuits shall be discussed in detail. Designing circuits using high-level functional blocks shall also be discussed. The course will closely follow the undergraduate curriculum existing in most engineering colleges.INTENDED AUDIENCE: Any Engineering Students/FacultyPREREQUISITES: Basic knowledge of electronics and electrical circuitslINDUSTRY SUPPORT: TCS, Wipro, CTS, Google, Microsoft, HP, Intel, IBM
