It has been a while since the last post and many things had happened to keep me away from posting. Luckily, things are calming down and I’m looking forward to resuming posting.

Since wireless technology owes so much to DSP, I thought that it was just fiting to create a mobile version of this blog. So, from now on, and thanks to the WordPress Mobile Plugin it will be possible to follow the Digital Signal Processing Blog from any web capable mobile phone. Enjoy it!

It has been a very long time since my last post, let’s just say that the time demands of modern life have not been very kind to me lately… In any case, good news is that the Holidays are giving me that extra time to catch up with this blog.

Some weeks ago I intended to write about an interesting technology to store information that is heavily based on DSP technologies. The idea behind the technology is quite interesting and a nice example of outside-the-box thinking. In a nutshell, the idea is to store information on a piece of paper by using color coding. More interestingly, since I read the first article about this, there have been more discussions about the validity and practicality of this idea.

From my point of view, the discussion is itself interesting because it brings up a lot of issues related to several DSP technologies. From the creative standpoint, I believe that although there are many challenges with this technology in its current form, who knows where it can end and where the related DSP problems may take us to? I guess, it’s about the journey, not the destination.
