Once again, I’m doing a bit of signal processing and, as usual, I found myself needing to brush up on the basics. And one of my favorite little tutorials is called Quadrature Signals: Complex but not Complicated. It’s written by Richard Lyons, who’s also the author of what I’ve been told is a good book on signal processing. I like the writing style – it’s fun and easy to read. Well, okay, honestly it gets pretty complicated by the end. But I still like it.
Last night I did my first cross correlation since 2008. Woo hoo! And it worked! Sort of. It still needs some tweaks, and I also need to improve my input signal. But it feels good to be using the signal processing toolbox in Matlab again 🙂 Once I get it sorted out a bit more, I hope to post the relevant snippets of code up here.
