Matlab toolbox for sigma-delta modulators

TIP: Richard Schreier's Matlab toolbox for the design and analysis of sigma-delta modulators can be downloaded for free from here. It works with R14 and higher.

If you ever work on the actual design of a sigma-delta modulator, this toolbox is immensely useful. It synthesizes the modulator given a noise transfer function, simulates the modulator for a given input, and also gives you realizable structures to implement the modulator. Plus a whole lot of other neat things. It comes with a very well-documented help file.

The Matlab Programming Contest

The biannual Matlab programming contest starts Wednesday May 11. Here is the notification from Mathworks:

The next MATLAB Programming Contest will run from Wednesday May 11 at 9AM EST through Wednesday May 18 at 5PM EST. We will post the challenge and the rules at the start of the contest.

As in recent contests, there will be three stages: darkness, twilight, and daylight. During darkness, both the code and scores for all entries will be hidden. In twilight, the scores will be visible but the code will still be hidden. When daylight arrives, all scores and code are visible.

We'll also be awarding several mid-contest prizes, including MATLAB baseball caps, T-shirts, and jackets, so don't wait until the last minute to participate.

If you have any questions or comments about the contest, send e-mail to
contest@mathworks.com. We look forward to seeing your entry. Good luck!
