Announcements and Frequently Asked Questions

• Apr 08 - Lab and Quiz 2 grades have been posted. If you see a zero there, it means I had no submission from you.
• Apr 07 - Some additional practice questions are posted. The Final Exam will take place at 14:00 on Apr 11, in VH 3009.
• Apr 30 - Assignment is posted. Due during our last class on Tuesday, April 5.
• Mar 21 - Lab1 deadline is extended to Tuesday 12:00 EDT. Submit either hard copy in person to CSE2001, or electronically via email (PDF is preferred, DOC is OK, but not DOCX; Excel sheet not needed). Include Frequency domain illustrations with short annotations for part 1.
  Quiz will take place on Wednesday, Mar 23.
  Also, there should be course evaluation at the beginning of Wed class.
• Mar 17 - In Lab1, the last two "hints" should apply to Q1.
• Mar 14 - Quiz will take place on Monday, Mar 21. Also, 1004A lab schedule (I'm generally not available on Thursdays).
• Mar 9 - The signal file and some directions for Lab 1 are posted (see below). Please let me know ahead of time when you plan to borrow the scope probes and the sound cable.
• Mar 7 - A very good explanation of Fourier transform operation in Excel.
• Mar 7 - Lab 1 and the spreadsheet are posted. The signal file is to be added shortly.
• Feb 28 - A good technical paper from Maxim Integrated Products, why one does not need to utilize the whole spectrum of the NRZ signal for the transmission. In fact, it's better not to:

  for most systems transmitting random NRZ data, 0.75 times the data rate is a good choice for the high-frequency cutoff

• Feb 28 - Reminder: course drop deadline is Friday, March 4, 2011.
• Feb 28 - Final exam date is posted.
• Feb 14 - More practice questions are posted. The Midterm will take place on Feb 16.
• Feb 2 - "Effective 1:00 pm, Wednesday, 02 February 2011, all day classes and evening classes have been cancelled and examinations postponed". Thus, there will be no class tonight.
• Feb 1 - Regarding the snowstorm expected on Wed, Feb 2. The current plan is to have the class as scheduled. However, if the roads look really bad, I might postpone the quiz; if I do that I will post an announcement here by Wed noon. In that case, we will just have a normal lecture (on Channel Characteristics and A/D conversion). Also, please motitor YorkU Weather status for weather-related university closures.
• Jan 28 - Practice questions are posted here. Most of them do not reqire any calculations. In those that do the calculations should be rather basic.
• Jan 28 - I have a copy of the course textbook that I can loan to a student until the end of the term (ideally, it should be shared among a few people). Send me an email if interested. FCFS. (UPDATE: one student has replied).
• Jan 12 - As was mentioned in today's class, the (now obsolete) 10Base2 thin coax cable Ethernet needs to be "terminated" on all open ends. Without proper termination, the transmitted signal could have multiple reflections from those unconnected ends, which would corrupt the data. On the following link you will be able to see what such reflections look like on oscillograms when a single pulse is sent into the cable (scroll half-way down to skip some technical stuff). With modern, twisted pair, star topology Ethernet the problems of this kind are rare.
• Jan 5 - First class, Introduction, Message & Circuit Switching. Software used today: GoldWave (as a spectrum analyzer for a microphone), inSSIDer (to display neighbouring access points)

General Information

• Distinction between information and data, between signal and data, between symbol and data, and between analogue and digital data
• Transmission media; time domain and frequency domain
• Fundamental limits due to Shannon and Nyquist
• Protocol hierarchies; the OSI model
• Encoding of analogue/digital data as analogue/digital signals
• Data link protocols; error and flow control
• Medium access; Ethernet and token passing systems in LANs
• Routing of packets in networks, congestion control
• Internetworking
