Abstract(in English) | We reported that the magnitude of line spectrum components is exactly estimated by FFT of a short data by concatenating a long null sequence to increase the number of sequence for the FFT.And it is found that there appear very conspicuous zero points in the speech spectrum analyzed by the method.This paper theoretically points out that the interference of two prominent sinusoidal components generates the zero points in the spectrum.The theoretical explanation is verified by the computer simulation. |
