All of us are familiar with the impact of modern digital computers , communication systems , digital display units , internet , emails etc .One of the main cause of this revolution is the advent of integrated circuits (ICs) which became possible because of the tremendous progress in digital as well as in analog electronics field . The operation of digital computers , communication systems , digital display units , internet , emails that has become the integral part of our daily life is based on the principal of digital techniques and these systems are referred to as digital systems .

The basic building block or units of digital systems are the various logic gates that you are going to study in this course.

This course is for both computer science engineering students as well as for electronics Students . The flow of this course is as below.

Introduction session (course syllabus)

Digital terminologies (what is input , output , what is a system , how to form input combinations for a system , formula , timing waveform)

You will also study about positive logic representation & negative logic representation .

Three classification of logic gates: Basic , Universal & Derived Logic Gates .

Basic logic gates : not / and / or .

Universal logic gates : nand / nor .

Derived logic gates : exor / exnor .

You will also learn about the universality of nand gate .

How nor gate is used to form all other logic gates .

In this course , Demorgan's first and second theorem has also been explained in complete detail .

You will also learn about the simplest application of logic gates: Buffer & Street Light Controller .

Lastly, I have given 4 logic circuit questions where we will perform steps by step approach to obtain the output expression.
