Course Content

• EE320 is audited by ABET
• Content is defined as part of curriculum
• Course as formulated here is part of Temples
  accreditation agreement with ABET
• Content is selection of subjects from text
• Selection is based on omitting overlap with EE300
• Topics included are selected to support
  curriculum
• EE320 is part of a degree program
• Material builds on prerequisites
• Material supports follow-on courses

10
The Term Project

• Continue with the start that you turned in with
  the first quiz backup
• Input
• Frequency sweep 1000 Hz to 3500 Hz
• Noise to obtain 20 dB SNR
• Sampling to obtain good performance
• Do NOT pitch your beginning and pick up the ADC
  to bitstream modules as a template
• Sample and encode/decode as instructed
• Measure BER vs. Eb/N0 as instructed
• Compare hard decoding with soft decoding

11
Topics (1 of 2)

• Propagation and Noise
• Modulation
• FDMA
• Pulse shading, power spectra, and FDMA

13
Other Topics

• Examples
• Antennas
• Some elements in Chapter 2
• Basic principles of antenna gain are given
• Supports the link budget equations
• Spacecraft constellation design Out of scope of
  the course
• Limitations and prerogatives
• EE320 has a lot of topics for 13 weeks time is
  tight
• Some controlled digression or exposition for
  context or to supplement the text material is
  good
• Time spent on unplanned material must not push
  planned topics out of the course

• Some of the longer or more difficult problems are
  marked as such here dont do them first
• If you have difficulty with a problem and cant
  resolve your problems with the text, put it aside
  and come back to it later
• In the event of difficulty
• If an example is given, go through it thoroughly
  first
• Re-read the text sections relating to the
  problems
• Put it aside and come back to it after you work
  others
• If the difficulty persists, send me an email
• Emails to the Professor
• Give the problem number
• State your difficulty as specifically as possible
