I compared SFT generated by Xavier's program and mine.
The power plots describe the difference between power computed from the output of two programs. The SFT plots describe the distance between two coefficients as complex numbers.
Two flavors of plots are available for comparison:
Power |
||
Entire frequency range |
||
|
|
|
200 Hz - 400 Hz |
||
|
|
|
250 Hz - 255 Hz |
||
|
|
|
251.25 Hz - 251.35 Hz |
||
|

|
|
|
250 Hz - 255 Hz |

Real part of Fourier coefficients in 251.25 Hz - 251.35 Hz |
