Phasors and the Propeller Analogy from Walla Walla University

We covered this excellent and very illuminating work before. As a follow-up, student Konrad McClure was kind enough to send me this video, which goes the extra mile with the propeller analogy. 

For me, the most interesting aspect of this is that it provides an explanation of the phase differences between upper and lower sidebands.   I need to study more about aliasing and the Nyquist criteria.  

Check out the video.  It get us a lot closer the an intuitive understanding;  math often falls short in this area. 

Thanks Konrad!
