The derivation and the examples of downsampling look nice, but you need to explain why decimator needs a lowpass filter before the downsampling. Also, you need to add a title for your page. | The derivation and the examples of downsampling look nice, but you need to explain why decimator needs a lowpass filter before the downsampling.

The whole slecture looks very clear and clean. But you might need to make each part more clear and separated. Also you can add a overview in the beginning to make reader easier to have a big idea of your slecture. And you need a title and a return link in the bottom oof the comment page. | The whole slecture looks very clear and clean. But you might need to make each part more clear and separated.

Your Slecture covers most of the topic and the graphs give a better understanding of the material. A good improvement would be adding the explanation of the low pass filter needed before the downsampling process.

Please post your reviews, comments, and questions below.
- Review by Yerkebulan Y.
In introduction, you forgot to mention that decimator also includes low-pass filter, also you did not clearly explain why low-pass filter is needed. Good explanation of derivation formula and clear graphs.

You forgot to put low-pass filter before the decimator. Except that everything is very clear and graphs and example of downsampling is easy to undertand. Great work!

The whole slecture looks very clear and clean. But you might need to make each part more clear and separated. Also you can add a overview in the beginning to make reader easier to have a big idea of your slecture. And you need a title and a return link in the bottom oof the comment page.

It would be nice if you added an example with a reason as to why you would want to downsample. I.e. not enough memory capacity for current sampled rate. Also, you didn't seem to explain much as to why a decimator needs a LPF prior to downsampling. Where you started explaining a limitation for the value of D to prevent aliasing, you could have added the LPF need background.
I also think you could have been more clear as to how each DT signal was derived. For example, you started in the picture with x[n] then D then x2[n], but then throughout the rest of the slecture you refer to an x1[n], so maybe making it clear that x1[n] is formed from a bandlimited CT signal x(t) that was sampled with period T1.
The graphs are done well and help draw together what you are doing, adding the LPF graph would be a great addition.
