| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We describe a problem with periodicity~(frequency) analysis by the discrete Fourier transform~(DFT). The DFT is the primary tool to detect periodicities in experimental data and has been used in a wide range of areas. However, there are cases for the DFT to not correctly identify periodicities that exist in the data, or, conversely, that the DFT detects periodicities that do not exist. We investigate this problem using data exhibiting $ 1/f $~power spectrum. |
