读进来WAV格式的语音数据，并绘制其波形，再播放WAV音频。-Reading into WAV format voice data, and mapping of its waveform, and WAV audio player.

无线通信中各种常用信号产生程序，里面具有BPSK，MFSK，QPSK，白噪声等波形产生程序，声称的波形何以存储为Wav文件或直接输出到声卡！适合短波数据通信编程参考！-Wireless communication signals in a variety of commonly used procedures, which have a BPSK, MFSK, QPSK, of white noise such as waveform generation process, claiming t

给定一个混有单频噪声的wav波形文件，设计一个滤波器，要求能很好的滤除掉单频噪声，并且对原声音信号的影响最小。这里仅仅要求FIR滤波器用窗函数法，IIR滤波器用butterworth实现。-FIR matlab filter butterworth

基于VB的串口通信和波形显示，数据存储界面。并附加了WAV音频文件的播放和显示功能。-VB serial communication based display and waveform data storage
