General remarks:
How can music CDs that have been scratched still produce perfect music? How does your smart phone get
the texts and videos? How do spacecraft out past Saturn communicate with Earth? And how do high quality movies fit on DCDs? All these depend on some pretty mathematics that is not too complicated and can be learned with minimal prerequisites, given the willingness to pick up some abstract algebraic, combinatorial, and probabilistic concepts.
This course develops basic ideas of information theory,
compression, and error-correction. It does not present a comprehensive
coverage of these topics. Instead, the stress is on basic concepts that
have cohesive mathematical foundations.
