Earlier this summer I gave a talk at RIT’s Summer Math Institute. This is a venue for STEM (science, technology, engineering, and mathematics) University and High School faculty to interact. One of the goals is to show to High School teachers how the concepts they teach are used in many of today’s technologies. So, my presentation was about explaining how most of what we do in DSP revolves around the simple operation of accumulating the multiplication of two sequences of numbers (plus complex numbers and trigonometry):

I think it is a nice way of introducing the basics of Digital Signal Processing to a general audience.

A couple of posts ago, I wrote about how DSP is a technology behind most of today’s technologies and advances. I also mentioned briefly the importance of volunteers for the IEEE. This post is closely linked with these two concepts.

As I mention then, the article “Signal Processing Inside”, inspired me to create this blog as a way of promoting the idea of “Signal Processing Inside”. It turned out that, after a couple twists of destiny, the blog led me into becoming an Associate Editor for the IEEE Signal Processing Magazine. Here, my role is to manage a permanent column called “In the Spotlight”. The column’s idea is to take news appearing in the mainstream media and present a technical discussion of the signal processing related to the news. For example, we have covered the recent (or maybe still current) worldwide financial crisis (by discussing signal processing methods to predict the evolution of stocks), or the H1N1 influenza outbreak (the topic was the study of the virus genome). We have also covered more technical topics such as the signal processing done at the Large Hadron Collider, part of the hardware installed in the last servicing mission to the Hubble space telescope and brain-computer interfaces. My role is that of deciding on the topics to be covered (in most of the cases), invite the authors and manage the writing of the article. For me, this has been a great source of personal satisfaction because I never imagined back when I was an undergraduate student, enjoying reading this magazine, that one day I would be managing an article in every issue. More importantly, I have learned a lot of things I didn’t know. So, although the time I dedicated to the column was one of the reasons I couldn’t post more often in this blog, this time will now pay off because I will discuss more signal processing inside topics in future posts here.
