  • Review by Miguel Castellanos

The steps you take to find each Fourier transform are well explained, and I really like your use of color to track the important changes from line to line. However, I think it would be clearer if you used different variables for the CTFT in terms of $ \omega $ and the CTFT in terms of $ f $, instead of using $ X $ for both. Good job!

The lecture is very clear and easy to understand. I think your lecture would of benefited by adding an clear outline introduction and conclusion. This would better lay out the overall idea of the lecture. The use of red text was an excellent way of showing the changes resulting from the substitution.


  • Review by Jacob Holtman

The objective is a little hard to understand at first and so the typo mentioned above is a confusing but once the purpose is understood then the examples are easy to follow and the layout makes sense. In the second example, it might be helpful to explain that there is a multiplication of $ 2 \pi $ over $ 2 \pi $.


  • Review by Fabian Faes

I thought that the examples and formulas were very well illustrated here and the use of color makes it easier to understand the flow of the steps. I also enjoy the fact that everything is nicely spaced out which makes it easier to read. I do agree that a small introduction and conclusion would be beneficial but it is not crucial if left as it is.


  • Review by Soonho Kwon
The introduction and the conclusion parts were not categorized. By categorizing the introduction and the conclusion parts, it would be easier to the reader to understand what is going on. Other than that the equations and the development were very clear and precise and it actually helped me understand this topic.
