===
- I suggest Wednesday at 3:30 or any time on Tuesday --Kellsper 22:47, 1 May 2011 (UTC)
- Any time Tuesday or Wednesday after 4 works best for me --Ssanthak 10:46, 2 May 2011 (UTC)
- OK, thanks for the input. How about Wednesday 5-5:45. -pm?
- That sounds good for me and Kara --Ssanthak 19:03, 2 May 2011 (UTC)
- Ok, let's do it then. -pm
- Where would this review session be? --Srigney 18:41, 3 May 2011 (UTC)
- I will just hold it in my office (MSEE342). If too many people show up, we will go to my lab (MSEE393). This will not be a formal review session: I will answer all the questions you have and go over the material you ask me to go over. -pm
Can a problem similar to Exam 2, Question 2 be posted using a CT signal rather than a DT signal? Thanks -cp

Your turn! A bonus point opportunity
All ECE301 students in Prof. Mimi's section have the opportunity to earn up to a 3% bonus on their course grade by contributing a Rhea page on a subject related to signals and systems. Examples of subjects are listed below. Feel free to come up with your own. To pick a subject, write your name next to it in the table below. Then when you begin writing your page, also post a link to it in the appropriate space (where it says "put link to your page here"). Your page will be graded based on content as well as interactions with other people (page views, comments/questions on the page, etc.). The number of links to other courses and subjects will also be taken into account: the more the merrier! Please do not simply copy the lecture notes and do not plagiarize. Read Rhea's copyright policy before proceeding.
