Synopsis
This course introduces the fundamental elements of analog and digital communication systems. The focus will be on the mathematical analysis of the signals and basic building blocks of communication systems. Performance of digital communication systems in the presence of noise will be discussed towards the end. The skills and knowledge gained from this class are essential for other advanced communication courses such as, data communications, computer network, digital communication systems, and mobile communication.

- Q: Can I make a brand new study sheet?
A: No.
However, if you think the old one is in a bad shape (falling apart), you can start with a photocopy of your own. (Reduction in size is not allowed though) - Q: What can I do if I lose my study sheet?
A: Dr.Prapun may be able to print out a scanned copy for you. (The writing won’t be as crisp as the original one but it’s better than nothing.) Alternatively, see below. - Q: I think the midterm study sheet (and the thing I wrote on it) is cursed (making me get poor score); I don’t want to see or use anything on it anymore. What can I do?
A: You may bring a brand new sheet for the final exam. However, you can only use one side of it.
- Basically, same rules as the midterm:
- Must be hand-written in your own handwriting.
- No small pieces of paper notes glued/attached on top of it.
- Indicate your name and ID on the upper right corner of the sheet (in portrait orientation).
- Do not modify (,e.g., add/underline/highlight) content on the sheet inside the exam room.
- Submit your A4 sheet with your exam.
- Violating the above instructions may cost you upto 10 pt.
- Use the returned study sheet from the midterm exam.
- Cover all the materials that we discussed in class and practice in the exercises and HWs.
- Material Distribution (score-wise): CH4 (30.5) + CH5 (18) + CH6 (17.5)

- Make sure that another side is blank. This will be used for the final exam.
- Submit your A4 sheet with your exam. (You will get it back before the final exam.)
- Q: I don't need any formulas. What should I do?
A: Bring in and submit a blank sheet of paper with your name and ID.
- Q: Can I use iPad or other devices with pen input to produce this?
A: Yes, but, again, all the content must still be hand-written in your own handwriting.
- Violating the above instructions will cost you 10 pt.
- Must be hand-written in your own handwriting.
