i was struggling a lot and this video helped me thank you very much.

Glad to hear that :)

This is a great lecture to show distortion when using a sampling rate lower than Nyquist rate and even equal to Nyquist rate. Would love to see the graph and how the special case [13:03] would change if F_s is 1 Hz higher. Thanks for these lectures! More power to your channel

Glad it was helpful! As I do not have the codes required for your question right now, you can download 'Interactive Demo of Nyquist's Sampling Theorem' by Costas Vlachos from Mathwork website. You can play around with it to any frequency you need :)

f = 1/3 where did this come from? 6.52

Acos(2*pi*f/n) is compared to 3cos((2*pi*n)/3) written in (ii) just above. Hence, we can see that, in the expression 3cos((2*pi*n)/3), f = 1/3

Hi Iffan, It's using the property of trigonometry that sin(2pi + theta) = sin(theta)
