I’ll follow up this post later on with some commentary, but I need to bookmark these videos. Chirp modulation was something I was aware of as a DSP programmer, but not something I grokked and really understood at the time. Most of my work was decoding FSK modulated Manchester signals.
This technology has a lot a lot of possibilities.
This first video gives a simple description and illustration of Chirp modulation in comparison to commonly understood modulation schemes.
This next video is more complex. Here, the presenter describes the mathematical basis for Chip modulation. It’s a bit hairy, but he breaks down some of the underlying concepts enough for mere mortals. “Mere mortal” meaning a familiarity with digital programming concepts, not necessarily a math wizard.
