This afternoon, I attended the first session of the five session “Signal Processing Fundamentals” class that my company is offering to all interested employees. I figured that since a few customers have inquired as to my knowledge of DSP’s (which is nonexistant at the moment), I figured I best sign up. Granted, this class covers the theory of signal processing rather than implementation, but I figure I can learn the latter on my own as I come to understand the former.

Today’s session consisted of a math review, going over the basic mathematical concepts (integration, differentiation, linear algebra, complex numbers, etc.) that are used in signal processing. Fortunately, it’s all stuff I learned in school. I was even surprised how quickly most of it came back to me. Matrix multiplication took a few seconds, but it eventually clicked.

Of course, there are things that I only vaguely remember. For example, I don’t remember all the methods for integrating and deriving more complex formulas. Fortunately, I was able to find a great website that helped with that.

I’m thinking that this weekend, however, I would be wise to try digging up a few of my old math books just for reference. Fortunately, I had the foresight to keep them. At least I hope I did. It’s possible I tossed them during the move. But I’m hoping I had more sense than that.
