JNTUH B.Tech 2nd year Switching Theory and Logic Design gives you detail information of Switching Theory and Logic Design Engineering R13 year subject. It will be help full you to understand you complete curriculum of the year.
Course Objectives
This course provides in-depth knowledge of switching theory and the design techniques of digital circuits, which is the basis for design of any digital circuit. The main objectives are:
- To learn basic tools for the design of digital circuits and fundamental concepts used in the design of digital systems.
- To understand common forms of number representation in digital electronic circuits and to be able to convert between different representations.
- To implement simple logical operations using combinational logic circuits
- To design combinational logic circuits, sequential logic circuits.
- To impart to student the concepts of sequential circuits, enabling them to analyze sequential systems in terms of state machines.
To implement synchronous state machines using flip-flops.
