Switching Theory and Logic Design

Lab outline:

To introduce the basic concepts and tools for design, testing and analysis of combinational and sequential digital logic and state machines.



Logic Design emphasizes development of procedures for the design of switching circuits, whereas Switching Theory studies properties of switching circuits and attempts to discover design procedures which make use of mathematical models and techniques to handle problems associated with the design of digital circuits. This lab provides an introduction to digital logic, starting with simple gates and building up to state machines. Students should have a solid understanding of algebra as well as combinational and sequential circuits including state machines. Using a digital logic laboratory kit with study guide, students will work through structured exercises where they will construct and test digital logic circuits; initially by studying and testing of 7400 series chips.

Labs will be built utilizing the following hardware:

  • Breadboards with associated items required such as wire, wire strippers and cutters
  • Basic 7400 series logic chips discrete components will be included only when necessary, with most of the labs using the standard 7400 series logic chips.
  • Simulation of various digital circuits using ORCAD (PSPICE Software).
