DFT 计算
实验步骤:
主界面下进入实验九的“DFT计算”的子实验。
输入取样点数,即有限长序列 x(n) 的长度。
输入信号表达式,或直接输入离散序列。
鼠标单击确定按钮,显示原序列及 DFT 系数的幅度、相位。(DFT calculation of the experimental steps: the main interface into the experimental Kau " DFT calculation of" sub-experiment. Enter the sampling points, that is, finite sequences x (n) length. Expression of the input signal, or directly onto a discrete sequence. Mouse click OK button to display the original sequence and the magnitude of DFT coefficients, phase.)

耳蜗实质上相当于一个滤波器组,耳蜗的滤波作用是在对数频率尺度上进行的,在1000HZ下,人耳的感知能力与频率成线性关系;而在1000HZ以上,人耳的感知能力与频率不构成线性关系,而更偏向于对数关系,这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
