This is seriously the best explanation on youtube for DTFT and also the relation between DTFT and FT. Why does this have less than 10k views?

[@adirem1983]

one of the best explanation series at this channel! you have the sence to visualise heavy intellectual stuff in theory and real life users in a sensual way there are many communication engineering people will give you standing ovations! please excuse my not native english writing.

[@jakeburchfield1864]

this is such a helpful video! it's really difficult to find good visual explanations of these concepts but you really did it well.

[@totally_not_a_robot1342]

Would it be possible for you to explain the Hilbert transform in a similar way? I really enjoy your way of explaining these concepts, thank you.

[@TheSiGuyEN]

sure

[@howwitty]

Great demonstration of FFT.

[@TheSiGuyEN]

this is DTFT. FFT is coming soon

[@user-fd8ob9gh3t]

Thank you.

[@konamuni]

Excellent sir.....which sw you used to show 3d animations

[@quitewhittle]

Please do a video on the Z-transform!

[@TheSiGuyEN]

in my checklist already

[@OP-do7rt]

lovely ♥️

[@longluo1788]

I like your explanation. Would you explain the z transform in future? Thank you.

[@TheSiGuyEN]

sure, after finishing Fourier

[@kaushalchari5686]

Can you explain what it means when the sampling time less than 1. do you mean it is less than 1 sec?

[@TheSiGuyEN]

which minute?

[@akrammohamed8374]

Are you egyptian by any chance?

[@mt5276]

when me grade 9 and this video appeared to me….. i wanna understand that lol but i see its to early for me

[@taurus_03]

I was here

[@TheSiGuyEN]

???

[@SumriseHD]

Me too!
