In addition, as a result of the transform is FFT the entire period of time, and time information points are not fully utilized; any sudden changes of the signal, the spectrum will be spread throughout the band.

In addition, because the FFT transformation is to the entire time section integral, the time information cannot obtain the full use; Signal any sudden change, its frequency spectrum will spread in the entire frequency band.

In addition, due to the FFT transform on the entire time period integration, timing information is not fully utilized; Any mutation of the signal, its spectrum spreading to the entire band.
