On Synthesis of Combinational Logic Circuits

Abstract

Objective of this paper is to present historiography of logic switching circuits. The research mainly focuses on chronological development and application of logic in the field of electronic and computer applications. This paper briefly discussed on the basic needs of logic synthesis and also discuss few interesting facts and design consideration regarding logic synthesis. It also enhances student’s deep understanding of different logic function minimization technique during a lecture and practical implementation.

Key takeaways

  • Digital switching circuits mainly concern with input variables, output variables and logic gates.
  • The introduction of indices by Mitchell into the logic algebra is the greatest technique use till now to represent logic proposition by symbol means of letter [3].
  • He also efficiently simplify switching circuit using algebra of logic and identify set of logic formula which are till now valuable for complex logical circuit minimization [12].
  • Using simple logic gate logic networks may be represented.
  • There are two useful techniques for reducing combinational logic expression and logic diagram to the fewest possible elements, these are mapping and minimization respectively.
