Scale to Shift (or vice-versa)

Dear students,
after the long (and admittedly confusing) discussion in last week's tutorial (w.r.t. Task Sheet 02, Task 2c), we found the following:
- The sample solution is correct (and not broken).
- You can get to it using either "shift then scale" or "scale then shift" (so math is also not broken, as we already said in the tutorial).
We are going to spend the end of the next tutorial showing you how to do it properly and how to minimize your risk of doing it wrong (all ways work, but with some you must pay more attention).
If you want to play around a little bit, feel free to apply the Fourier definition directly to the signal and try to get to the sample solution (without applying correspondencies).
So again, apologies for the confusion and see you all on Friday when we get this thing clear!
Best regards
The DTSP-Team
