Overview - Course on Digital Electronics for GATE and IES

In this lecture, I have covered basics of Boolean Algebra and various important identities and laws like Transposition Theory, Demorgan's Lab, etc.

Boolean Algebra

In this lecture, I have talked about the SOP, POS and Canonical Forms of a boolean espression.

SOP, POS and Canonical Forms

In this video, I have taught about positive and negative logic and how to find dual and complement of a boolean expression.

Dual and Complement of a Boolean Expression

In this video, I have covered various types of Logic Gates.

Logic Gates - I

In this lecture, I have covered the basics of two and three input EXOR Gates and we learnt how to use XOR Gate as a Buffer and Inverter and derived some identities in respect of XOR operation.

EXOR Gate

In this lecture, I have covered the basics of EXNOR Gate, how to use EXNOR Gate as a Buffer and Inverter and the comparison between multiple inputs EXOR and EXNOR Gates.

EXNOR Gate

In this video, I have talked about Universal Gates, why they are called so and how to implement other Logic Gates from the Universal Gates.

Universal Gates

In this video, I have taught how to implement any boolean function with NAND Gate or NOR Gate.

Implementation using NAND and NOR Gates

In this video, I have covered the basics of Combinational Logic circuits and then implemented the Half Adder.

Introduction to Combinational Circuits + Half Adder

In this video, implementation of Half Adder and Full Adder is discussed

Full Adder

In this video, we discuss about how to perform a n bit addition and then implemented a 4 bit Binary Adder.

Parallel Adders

In this video, I have talked about how to implement a Look Ahead Carry Adder and what advantages it offer over a binary parallel adder

Look Ahead Carry Adder

In this lecture, we have discussed the basics of Multiplexer.

Introduction to Multiplexers

Multiplexer as a Universal Gate

This lecture covers the basics of De-multiplexers. We have talked about the operation of 1x2 and 1x4 Demux and also looked into how to implement higher order Demux from lower order Demux.

Demultiplexers

This lecture covers the basics of Decoder. Here, we have discussed the operation of 2x4 and 3x8 Decoder and also learnt about how to implement any boolean function with the help of Decoders.

Decoders

This lecture covers the basic operation of encoders. Here, we have discussed the operation of 8×3 encoders and talked about the limitations of such encoders.

Encoders

This lecture talks about the priority encoders and  the operation of 8×3 Priority Encoder and 4×2 Priority Encoder have been covered in  detail.

Priority Encoders

In thos lecture, we have covered in detail the operation and design of BCD Adder using a 4-bit binary adder.

BCD Adder

In this lecture, we have talked about the Excess-3 Code and understood the meaning of weighted and unweighted code. We have also discussed about how to calculate the R's complement and (R-1)'s complement for a given number system with base R.

Excess 3 Code

In this lecture, we have solved the questions asked in the GATE 2018 Exam from Combinational Circuits.
