ECE 390 Educational Objective

• Graduates of ECE 390 will have a basic
  preparation in analog and digital communications.
  
• They will have basic knowledge and analysis
  skills applying to AM, FM, and digital
  communications. This prepares them to
• Take EE 488 performance of these systems in the
  presence of noise. This can be a path leading to
  graduate studies in Wireless Communications.
• Function as computer engineers and system
  designers
• Prepare for careers in Telecommunications
  Industry

ECE 390 Classical Careers in Telecom ?

• Not a sure thing like it used to be

ECE 390 Careers in ECE and CompE !

• On the other almost every computer or other
  electronic system nowadays involves
  communications technology and theory

• My car has a remote keyless entry
• Your keyboard may be wireless
• My printer has an InfraRed port
• Soon my fridge will have an IP address !
• Theres a LAN in your family car. And on the
  power lines in my house.
• I can play radio channels on my computer
• All images, sounds, movies are digital
• The I/O channel to a hard drive uses line coding
  and adaptive equalization...
• etc. etc. etc.

The message is .

• System Designers, Computer Engineers, Electronics
  Designers (not just Communication engineers)
• all need a grounding in Communication Systems.
• This is probably the best real reason to take ECE
  390 (and the reason it is now a core course for
  ECE degrees.)

But isnt AM and FM pretty old stuff .?

• Digital is hot (and elegant !)
• But why FM and AM ? Arent they really old and
  only for our radios?
• Not really...
• Today we use AM and FM (PM) to carry digital
  signals.
• AM is also the basis of all digital lightwave
  transmission today
• and FDM is the basis of DWDM optical networking
• FM (PM) is the basis of many other high
  performance communication systems, including when
  the payload is digital.
• And remember..Everything is actually ANALOG
• ANALOG Linear High performance !

Relationship to Other Courses

• EE 488 Communication in Noise
• EE 486 Optical Fiber Communication
• EE 489 Telecom. Systems Engineering
• and at the Grad Level
• Digital Communication systems
• Data Computer Networks
• Survivable Transport Network Design
• Multi-Media Systems

Cheating

• Dont ! It matters !
• I care and you should care too.
• There is a crack-down on at U of A
• It is against the oath you will swear when you
  get your Iron Ring
• If you know of cheating you are obliged to advise
  me
• Dont put a red light on your career

(My apologies to all those of you that wouldnt
even think of it)
