Questions and Comments for Frequency Domain View of Upsampling
A slecture by exchange student from UNAM, Mexico, Michel Olvera.
Please post your reviews, comments, and questions below.
- Review by Miguel Castellanos
- Your introduction gives a great preview of the concepts that you cover in your slecture. I also like how you included some practical examples, which are a great way to relate the course material to real-world applications. A small discussion about aliasing would be nice to see since this is always a concern when dealing with DT signals. Excellent job!

- Review by Yerkebulan Y.
In Introduction, I think, you should provide graphs to show how you inserted zero-valued samples. Good explanation of using LPF graphically, which was not in the lecture notes. Some minor spelling errors. At the end you listed very interesting practical application of upsampling like in audio signals and images.

- This was a good slecture. I agree with some of the reviews above. I think you should make some graphs to demonstrate the interposed zeroes. Otherwise the other concepts were demonstrated and explained well with the graphs. I think that including an explanation of the various cases where aliasing can occur. I enjoyed the practical application portion of the slecture. It shows the usefulness of the content.
- Review by Andrew Pawling
Very good slecture. The material is very clear and concise. I really liked the practical examples and really help readers better understand upsampling. The plots are very nice and easy to interpret. Good job!

- Review by Soonho Kwon
It would have been better to illustrate how the zero padding works. Other than that, I loved your introduction, which literally explains most of the topic. Also, your example and conclusion part was also very clear to understand. Great job.

Good job first! As other reviews say. Graph will be much more helpful to show your point. You did have very good explanation about how to use low pass filter when doing upsampling. In the end, the practical example is very good to have a deep understanding about the upsampling.
- Review by Hyungsuk Kim
I thought that this slecture is great. Every basic concept about upsampling is well explained in introduction. And example of upsampling is well explained in graphically. However I think you should make LPF gain of 2 as you written in the block diagram.
