I feel like your video's must be aliasing because there's no way a 16 minute video on signals processing actually felt more like an 8 minute video on it... Or maybe it's just harmonics. Either way great explanation, the wheel idea is a brilliant way at quantitively explaining it.

Thanks. I love your comment 🤣 I'm going to use that if anyone ever tries to tell me signal processing is boring.

Not what I was looking for, but I found it very interesting and I’m watching anyway Thanks for sharing!

Glad you enjoyed it anyway!

I knew the math behind it and also knew practical effects of aliasing but wasn't quite sure how they were connected. This helped. Thanks!

Glad it helped. And this is another video I made on the topic, with more real-world "visuals": "How to Understand Aliasing in Digital Sampling" kzfaq.info/get/bejne/r52FgrSQxqydc2Q.html

actually it's not your eye that has the lowpass filter. It's a structure of your thalamus called the lateral geniculate nucleus (LGN)

Can you make a video on Spatial Aliasing in Uniform Linear Array?

@iain_explains Жыл бұрын

I've got a video that shows the spatial aliasing, although I didn't describe it with that term, so you might like to watch: "How does Antenna Spacing affect Beamforming?" kzfaq.info/get/bejne/l9OVo9yXnpOpYas.html
