Quite a few of you have commented that the diagram at 8:33 is incorrect, and that you can in fact reconstruct a perfect sine wave, not a "wonky" one like I've drawn. Turns out, they're right, but only when certain specific conditions are met. For a full discussion on this point, check out the following video: kzbin.info/www/bejne/iZPCZYCJbdFrr68

Thanks. I am 60+ years and I learnt something today. The way you broke it down Now the reason why i watched this was to understand sampling when it comes to astronomical imaging. In Astronomical imaging, it's not how often you sample but the pixel size of the sensor in relation to the object you are imaging. for example to my understanding if you are imaging the planets then you pick a larger pixel size and if you do deep sky images ( of stars, galaxies, nebulae) you use smaller pixels.With the knowledge you have given which is very useful, I will try to now improve my understanding of this subject. Thanks again.

Hello and thank you very much for your comment! It was lovely to see you reason out the connection there to pixel size - Yes, in photography, we're doing *spatial* sampling as opposed to *temporal* sampling. Of course there are many other factors, such as the lens' ability to collect light, its aperture size and so on. But the basic intuition of course is - If something is significantly smaller than a pixel, all you're going to see is a speck of light, but no useful shape to work with.

This was so much more helpful than my time spent studying this concept at SAE. I really appreciate the almost conversational and natural progression of your explanation. Rather than stopping the momentum of each point to recite and emphasize technical language, you convey the overarching process before tying everything to the (occasionally intimidating) terminology. This is an excellent way to communicate these concepts. Great job.

Hello and thank you for your comment! It's unfortunate, but I realize that teaching in a classroom is never easy because you never have enough time and there's always more to explain. Oh well, regardless, I'm glad I could fill in the gaps for you!

You're welcome! It's unfortunate, but sometimes in university, professors have to cover a lot of the underlying theories and math, so that's why you feel they aren't as good. I don't blame them, but I'm glad I could help you fill in the gaps!

Thank you so much for this amazing video. I am doing Frequency Modulation on Simulink & I came across Nyquist Frequency Limit problem. Now I know that my Sine Wave block, I used low sample time (Ts), which results in low Sample Rate (aka Sample Frequency, Fs) which results in low Nyquist Frequency Limit [0 ---> Fs/2].
