模拟单边带调幅及解调产生300 ~ 3400Hz的调制信号，画出时域波形及频谱；  产生载波信号，频率自定义，画出时域波形及频谱；  产生加性高斯白噪声，画出时域波形及频谱；  单边调幅，画出叠加噪声后的调制信号和已调信号的波形及频谱；  设计滤波器，画出幅频响应图；  解调，画出解调后的信号时域波形及频谱，并对比分析。(Simulation of single sideband amplitude modulation and demodulation )

matlab包括最基本的语音处理程序（如谱减法，谱幅度估计，语谱图等）以及语音库(Located in this Prentice Hall web site compartment are functions, scripts, workspaces, and data required by the MATLAB exercises in the text: Discrete-Time Speech Signal Processing: Principles and Practice. Note that the speech files given are often specific cases of a certain class of speech signal, i.e., the waveforms often can be replaced by other examples with similar characteristics that serve the instructive purpose of the exercise.)
