6.02 Handouts

Lectures The course notes ("text") are in three parts, reflecting the three themes in 6.02: bits, signals, and packets. Each part has multiple chapter. The table below specifies the relevant chapters and/or sections for each lecture. Please send any questions/comments/suggestions on the notes to hari.

  • Part 1: Bits: Chapters 1~8
  • Part 2: Signals: Chapters 9~14
  • Part 3: Packets: Chapters 16~19

    Occasional notes from recitation sections The recitation instructors' personal notes are provided by them when and if they feel these may be helpful for a particular recitation, but please don't count on there being notes from each (or even any) instructor for each recitation. Also, each recitation instructor has considerable latitude in determining his teaching plan and choosing problems for discussion. Some of this material may be specific to a particular section, and such material will not be required for the quizzes or problem sets.

    Background and other readings The following material may be useful as background or augmentation. They are not required for the course per se.
