This is a overview lesson of Digital Electronics regarding what will be covered in this course with the targeted audience and the course outcomes.

Overview (in Hindi)

This lesson gives introduction to different number systems available and used. Here I have talked about the counting in different number systems like octal, hexadecimal, binary and decimal.

Introduction to Number Systems (in Hindi)

In this lesson various number system conversions are explained in detail with examples. I have talked here about Binary to Decimal, Octal to Decimal, Hexadecimal to Decimal and Decimal to Binary Conversions.

Number System Conversions -I (in Hindi)

In this lesson rest of the number system conversions are explained. The conversions covered are Hexadecimal to Binary, Octal to Binary etc.

Number System Conversions -II (in Hindi)

In this lesson Binary number representation in different forms like Sign Magnitude representation, 1's complement representation and 2's complement representation is explained in detail.

Signed and Unsigned Binary Numbers (in Hindi)

This lesson explains the necessity of Binary codes with thorough evaluation of Binary Coded Decimal Codes. Here the different conversions of Binary to BCD and BCD to binary are also explained in detail.

BCD Codes

This lesson explains the need for Excess-3 codes. Here the table of different XS-3 codes is given in detail with the conversions of different XS-3 to decimal or vice versa.

Excess-3 Codes

In this lesson a brief description behind the evolution of Gray Codes is given. Then conversion of binary to Gray and Gray to binary is explained in detail with example.

Gray Codes

This lesson gives brief overview of the requirement of Alphanumeric codes. The different types of alphanumeric codes are also explained in detail with their tables.

Alphanumeric Codes

In this lesson the basic principle behind arithmetic operations on decimal numbers is explained and same principle is used for arithmetic operations on binary numbers .

Digital Arithmetic

A detailed explanation of rules of Excess-3 code addition and subtraction are explained with examples.

Excess 3 Arithmetic

This lesson is dedicated to boolean algebra laws like associative, distributive , commutative etc. I have also covered duality and DeMorgan's theorem here in detail.

Boolean Laws

Various logic systems i.e. positive and negative logic systems are explained in detail with examples. I have also defined truth tables and boolean expressions.

Binary Logic System

This lesson defines the Logic Gates. Here a brief description of basic logic gates i.e. Not, And & Or gates with examples is given.

Basic Logic Gates

Full derivation of different boolean laws is given here with some simple examples.

Laws to Remember

Universal gates are defined in brief with NAND gate in detail. I have also realised basic logic gates through NAND gate.

Universal Logic Gates- NAND Gate

This lesson is dedicated to the concept of NOR gates with its truth table explained in different ways. Also various basic logic gates have been realised using NOR gate.

NOR Gate

This lesson covers the need for Exclusive Gates. The different types of Exclusive Gates are explained in detail with truth tables.

Exclusive Gates

This lesson covers problems on realising Boolean Expression using logic gates.

Vishesh Maheshwari

In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or lossless. This course is about various compression techniques, and related algorithms.

Data Compression Techniques and its Algorithm
