The "learning curve" for learning software defined radio is more than steep, it can be an impenetrable cliff! I’ll share my journey and the path I found up that cliff to reach an understanding that I could work with and tie into the weird mathematics I was being told were responsible for it. Once you have a foot hold, you can make visible progress in your journey of understanding. We’ll start with my first implementation of the FFT and the questions it raised and go from there until we run out of time.
