  • 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!

    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.
