Important Topics In Digital Logic Study Notes for GATE & Computer Science Engineering Exams

By Kajal Vats|Updated : December 4th, 2020

Digital logic is nothing but representation of signals and sequences of a digital circuit through  numbers. It is the basic for digital computing and provides a fundamental understanding on how circuits and hardware communicate within a computer. Here is the list of some important topics of digital logic so that one can focus on these topics while preparing and prepare accordingly.

  • Boolean Algebra and Minimization
    • Binary Representation/ Codes
    • Binary Arithmetic
    • (r-1) & r's Complement
    • Logic Gates
