  • Review by Jacob Holtman

There should be a mathematical definition of down sampling and not just a graphical one. Also the points that are kept in the second graph should be explained better and not left to the reader to find. The equations are very well set up and it is easy to follow the logic. Also the example helps to explain why a filter is needed and limitations.

  • Review by Andrew Pawling

I agree that it does need a mathematical definition of down sampling. The plots are good and help illustrate the down-sampling. The Mathematical explanation is very clear and concise. The explanation of why the low-pass filter is needed is also good. Great job!
