This is the approach taken by most textbooks and I am not a fan of this approach so I can't really make any recommendations. If you are looking for a "meaning' of the DFT, I recommend you read my second blog article "DFT Graphical Interpretation: Centroids of Weighted Roots of Unity". This same "wrapping" interpretation can also be applied to the continuous case and give you a differenct conceptual framework to relate the DFT to the FT. | |
