| + | == Slecture Review == | ||
| + | |||
| + | Guidelines | ||
| + | |||
| + | *You must review one slecture per topic. (You cannot review your own slecture, of course. So if you are the only person who completed a slecture on a given topic, then you are not required to write a review for that topic. ) | ||
| + | *The maximum number of reviews for each slecture is written next to each slecture. First come first serve. You will notice that some slectures will not get any reviews. This is because the slecture was either not completed or did not include a question page. | ||
| + | *Write your review directly on the question page of the slecture you are reviewing. Let me know if you want an anonymous login. | ||
| + | *You can reserve a spot for a specific slecture by writing your name on the question space. | ||
| + | *Be nice! Be constructive! The authors worked really hard on this. | ||

Slectures
The cleaned up version of the slectures is here.
Post a link to your slecture page below the relevant topic. If you want to reserve a particular topic, write your name/nickname below the topic. Please no more than 4 students per topic. To build your slecture page, you should use the following templates.
- Template for text slecture
- Template for video slecture
- Template for question page (use the same template for both video and text slectures.
- Topic 1: Fourier transform as a function of frequency ω versus Fourier transform as a function of frequency f (in hertz). (Make sure to give some examples, including some signal whose FT nvolves Dirac delta(s). For that signal whose FT involves Dirac delta(s), compute the FT two different ways: 1) by starting from the ECE301 FT pair and making a change of variable, and 2) using the CTFT formulas. Observe that the expressions for the FT are different. Then point out that one can transform one expression into the other using the scaling property of the Dirac delta.) DEADLINE September 19
- Text slecture by Dauren 15 reviews needed here.
- Text slecture by Randall Cochran 15 reviews needed here.
- Topic 2: Definition of the "rep" and "comb" operators. (Note that there are two ways to define each of these operators: using multiplication/convolution with an impulse train, or using a summation formula without impulse-train. You should include both representations and explain how to go from one to the other.) DEADLINE September 19
- Text slecture by Xiaozhe Fan 30 reviews needed here.
- Topic 3: Fourier transform of "rep" and "comb". (Make sure to carefully explain how to compute the Fourier transform of an impulse-train. You do not need to prove the multiplication/convolution property of the CTFT, but state it clearly whenever you need to use it.) DEADLINE October 1

Slecture Review
Guidelines
- You must review one slecture per topic. (You cannot review your own slecture, of course. So if you are the only person who completed a slecture on a given topic, then you are not required to write a review for that topic. )
- The maximum number of reviews for each slecture is written next to each slecture. First come first serve. You will notice that some slectures will not get any reviews. This is because the slecture was either not completed or did not include a question page.
- Write your review directly on the question page of the slecture you are reviewing. Let me know if you want an anonymous login.
- You can reserve a spot for a specific slecture by writing your name on the question space.
- Be nice! Be constructive! The authors worked really hard on this.
A bonus point opportunity
Students in ECE438 Fall 2014 have the opportunity to earn up to a 3% bonus by contributing a Rhea page on a subject related to digital signal processing. To pick a subject, simply write your name next to it. 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.

Honors Contract
Students pursuing the honors track have the option to honors contract ECE438. Sahil Sanghani was interested in medical applications of DSP, so he wrote slectures on the relevant coursework from ECE 637, Digital Image Processing. Access the slectures here.
