Thank you for posting this. I work around a lot of RF equipment, but I only know DSP at the highest and most basic level. I’m hoping this will help me gain a working knowledge of it.
I feel the same way - which is probably why I also found this interesting.
Another resource I really liked is Practical Signal Processing. It is also a practitioner focused treatment of the material, with enough theory to make you dangerous. It’s been a big help for me in understanding the DSP components of GNU Radio flow-graphs. It doesn’t necessarily cover details on the internal implementations of different processing stages but is great to come up to speed on discrete steps in a processing pipeline.
