A Visual Introduction to DSP for SDR (switchb.org)

Thanks, I found this to be very useful! I've been trying to learn about physical layer networking and been reading a communication systems textbook (the one by Haykin), and being able to visualize the different transformations on signals was super useful.

The section on FIR, IIR, and how to make high-pass and low-pass filters was also useful to me. I have a decent math background, so I'm finding one of the hardest parts of working through an intro communications textbook is figuring out the EE jargon (in-phase and quadrature, narrowband and wideband, etc).

I highly recommend whole Cyberspectrum series, or attending live if you are in the area.
