I have really failed to get around to blogging what I've been doing lately, which is all software-defined radio. Let's start fixing that, in reverse order.

Yesterday, I went to a Bay Area SDR meetup, “Cyberspectrum” organized by Balint Seeber and gave a presentation of visual representations of digital signals and DSP operations. It was very well received. This video is a recording of the entire event, with my talk starting at 12:30.

Love your live charts -- really helps visualise complex signals!

How did you make them? Is it all javascript? What is it running in....doesn't look like powerpoint!

It's a single web page, and the code is all custom except for using the MathBox.js graphics framework (which provides axes and things like "show an animated curve using this function to compute the points".

Thanks very much.

Your presentation is really excellent -- not just the material but the explanations you give. I've been reading and watching a lot of under-lying theory (trying to refresh all the great stuff I've forgotten since University) around SDR and your presentation really nails it and helps understand it all -- really awesome.... Massive thank you.
