Therefore, when the sampling frequency or the signal can not meet the above conditions, the use of fft analysis will produce "sidelobe" and "spectral leakage" phenomenon, to the analysis error.

Therefore, when sampling frequency or signal does not meet the above conditions, use FFT analysis results in a "side-lobe" and the "spectral leakage, to bring about error analysis.

Therefore, when the sampling frequency or the signal cannot satisfy the upper row condition, using the FFT analysis can produce “the side lobe” and “frequency spectrum divulging” the phenomenon, brings the error to the analysis.

Therefore, when the sampling frequency or signal when the above conditions cannot be met, using FFT analysis will have a "flap" and "spectrum leakage" phenomenon, brought to the analysis of error.
