说明：  录制一段个人的语音信号，并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，采用双线性变换法和窗函数法设计滤波器，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；最后，设计一个信号处理系统界面。(Record a personal voice signal, and recording the signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum for a given filter performance, the bilinear transformation and design of filter window functions and draw the frequency response filter then filter of their own design collection of the signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, analysis of signal changes playback audio signals Finally, a signal processing system interface design.)

用matlab实现对一段语音数据的语谱图（窄带和宽带）的画图分析(Spectrogram of a voice data (narrowband and broadband), drawing analysis using matlab)

说明：  进行潮汐调和分析，计算各分潮的调和常数，判断该站点的潮汐类型，并预报未来潮高。(Through tidal harmonic analysis, the harmonic constants of each constituent tide are calculated, the tidal types of the station are judged, and the future tidal heights are forecasted. Conducting tidal harmonic analysis)
