Giridhar’s book is not a dry compendium of theorems; it is a designed to make the reader feel the ideas.
Before diving into specific resources, it’s essential to understand the two pillars of this subject: information theory and coding by giridhar pdf
: The measure of information associated with a specific event is inversely proportional to its probability. It is calculated as
This sets the theoretical limit for compression algorithms like Huffman Coding and Arithmetic Coding. If your average code length is below Entropy, you are losing data (lossy compression).

The mathematical limit on the maximum amount of error-free data that can be transmitted over a noisy channel.
From the lossless compression algorithms we use to zip files on our computers to the advanced channel coding that ensures our video calls don't drop in areas with poor reception, the principles of information theory and coding are everywhere. Educational materials that methodically unpack these concepts—from the basic mathematics of entropy to the complex algebraic decoding of cyclic codes—serve as the foundation for the next generation of telecommunications and software engineering.
