1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的滤波器对采集的信号进行滤波,画出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化 回放语音信号。2.(1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech signal time-domain waveform and frequency spectrum performance for a given filter, mining matlab digital filter design, and draw the filter frequency response then use their own filters designed to filter the collected signals, to draw the filtered time domain waveform and frequency spectrum, and comparing the signal before and after filtering, analysis of signal changes playback of audio signals. 2.)

说明：  二分法检索（binary search）又称折半检索，二分法检索的基本思想是设字典中的元素从小到大有序地存放在数组（array）中， 　　首先将给定值key与字典中间位置上元素的关键码(key)比较，如果相等，则检索成功；(Dichotomy search (binary search), also known as binary search, the basic idea of ??dichotomy is set to retrieve the dictionary from small to large elements stored in an orderly array (array), the first key the given value on the middle element of the dictionary The key code (key) comparison, if they are equal, then the retrieval success )

说明：  广义S变换 作为小波变换和短时傅里叶变换的继承和发展， S 变换采用高斯窗函数且窗宽与频率的倒数成正比，免去了窗函数的选择和改善了窗宽固定的缺陷，并且时频表示中各频率分量的相位谱与原始信号保持直接的联系，使其在 PQD 分析中可以采用更多的特征量，同时， S 变换提取的特征量对噪声不敏感，因此，近年来众多学者纷纷采用 S 变换并结合其他分析工具应用于 PQD 的分析，产生了大量研究成果。(Generalized S-transform)
