PySDR: A (Free) Guide to SDR and DSP using Python

Dr. Marc Lichtman has recently released his free online PySDR guide to Digital Signal Processing (DSP) explained with the help of software defined radio and Python code. Over the years we've seen numerous SDR & DSP courses come out, some requiring payment and some free. We note that this guide is completely free, and appears to be one of the better if not the best guide in terms of explaining DSP fundamental concepts in an easy to understand way. A lot of visualizations and animations are used which really help anyone new to the subject.

While the explanations are very good, please note that this is still a technical University level guide intended for Computer Science or Engineering students, so prerequisite knowledge is required. Dr. Marc recommends it for someone who is:

1. Interested in using SDRs to do cool stuff
2. Good with Python
3. Relatively new to DSP, wireless communications, and SDR
4. A visual learner, preferring animations over equations
5. Better at understanding equations after learning the concepts
6. Looking for concise explanations, not a 1000 page textbook

The SDR hardware used in the book examples is the PlutoSDR which is a fairly low cost SDR intended for use by students. However, the PlutoSDR isn't required as most of the code examples use generated data.
