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(Cochlear substantially equivalent to a filter set, cochlear filter is used 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 )

说明：  数字信号处理设计与仿真分析 (1)建立两个模拟信号的数学模型 sa1(t)和 sa2(t)， 其中 sa1(t)是有用信号， sa2(t)是干 扰信号。 两个信号的中心频率、信号带宽等参数由学生自己选定，要求两个信号的频谱不重 叠， sa2(t)的幅度比 sa1(t)的幅度高 20dB， 两个信号时域叠加得到合成信号 xa(t)， 即 xa(t)= sa1(t)+ sa2(t) 设计计算机程序仿真产生 sa1(t)、 sa2(t)、 xa(t)信号， 分别画出三个模拟信号的时域波 形和频谱图；(Establish two mathematical models of analog signals sa1(t) and SA2 (t), where SA1 (t) is the useful signal and SA2 (t) is the dry signal Interference signals.)
