List of Topics for Midterm 1

The midterm will be a multiple-choice exam. There will be about 30 – 45 questions.  The questions will be grouped into three buckets.

  1. C style questions. These are the easiest.
  2. B style questions. These are the more difficulty
  3. A Style questions. These are the most difficulty ( These are designed to challenge you_

The topics that will be covered are outlined below.

  1. Difference between simplex, half-duplex and full-duplex.
  2. FM and AM modulations.
  3. Baud Rate Calculations, Given some baud rate (Symbols per second) how many bits be second. (Other examples and questions along this line_
