What This Document Is
These are lecture notes from ELENG 122, Introduction to Communication Networks, at the University of California, Berkeley. They focus on the foundational principles established by Claude Shannon, a pioneer in information theory. The notes represent a core exploration of how information is quantified, compressed, and reliably transmitted across various communication channels. This material delves into the theoretical limits of communication systems, providing a basis for understanding modern network design and performance.
Why This Document Matters
This resource is invaluable for students enrolled in introductory communication networks courses, or those seeking a strong theoretical grounding in the field. It’s particularly helpful when you’re grappling with the fundamental concepts that underpin all digital communication. Use these notes to supplement textbook readings, prepare for more advanced topics, or review key ideas after a lecture. Understanding these principles is crucial for anyone pursuing a career in electrical engineering, computer science, or related disciplines.
