6.02 Introduction to EECS II: Digital Communication Systems
6.02 Introduction to EECS II: Digital Communication Systems (Fall 2012, MIT OCW). Instructors: Prof. Hari Balakrishnan and Prof. George Verghese. An introduction to several fundamental ideas in electrical engineering and computer science, using digital communication systems as the vehicle. The three parts of the course - bits, signals, and packets - cover three corresponding layers of abstraction that form the basis of communication systems like the Internet.
The course teaches ideas that are useful in other parts of EECS: abstraction, probabilistic analysis, superposition, time and frequency-domain representations, system design principles and trade-offs, and centralized and distributed algorithms. The course emphasizes connections between theoretical concepts and practice using programming tasks and some experiments with real-world communication channels.

| Lecture 14 - Spectral Representation of Signals |
This lecture starts with a demonstration of echo cancellation using deconvolution, and then continues to cover the spectral content of signals. Fast Fourier transform, and the effect of a low-pass channel are also discussed.
