8.2.6 Part 1 Wrap-up

TL;DR

This comprehensive analysis covers the main topics discussed in a course on design tradeoffs in digital systems.

Transcript

This discussion of design tradeoffs completes Part 1 of the course. We've covered a lot of ground in the last eight lectures. We started by looking at the mathematics underlying information theory and used it to help evaluate various alternative ways of effectively using sequences of bits to encode information content. Then we turned our attention ... Read More
