Your way of explanation is outstanding

[@dddderek]

What a teaser! I can't wait for the full video!!! Thank you so much for making this content. 👍👍👍

[@MarkNewmanEducation]

You're welcome. Working on the full version as we speak. It should be out before the end of July.

@@MarkNewmanEducation I graduated in EE 26 years ago, #1 in my class, but didn't truly, intuitively understand anything. Now, so much later in life, I'm becoming passionate about understanding things from the ground up, in my gut, through and through. Your videos are tremendously helpful, and I wish I had a teacher like you back in my college days.

Very educative one here ,Mark,Thank you.

[@MarkNewmanEducation]

[@MarkNewmanEducation]

Will do. I'll make a note for future videos. Thanks.

At 1:16, shouldn't a pure sine wave only be formed by sine components?

[@leonardomaia7661]

a sin wave is equal a cos with a phase of -pi/2

[@francoisgarcia7457]

Thanks for these interesting videos!

At 04:10, why is the - 0.32 pointing to that time specifically. Most certainly, then there will be more 5 & -5 Hz frequencies corresponding to other times in the IFT list. Is that correct or have I missed something?

[@MarkNewmanEducation]

In the example, I simply calculated the instaneous value for a random point in time using the inverse Fourier Transform. The 5 and minus 5 Hz frequencies can be calculated for any point in time and they will give a different value depending on the value of t. I just chose one particular value of t for the example.
