用vc编的用于语音的频谱的检测，可以显示语音的频谱图。-It is used to detect spectral of speech and display the spectralgram.

实现语音的采集、量化、控制、频谱显示功能。整个程序是通过windows平台下，使用VC++6.0的库函数实现声卡的信号采集从而生成wave文件；之后，对信号进行FFT，并在windows窗口下完成频谱显示。-Voice of the collection, quantification, control, spectrum display function. The whole process through the windows platform, the use of VC++ 6.0 o

基于VC++的数字通信系统仿真，实现了数字通信过各个环节，能观测到个环节波形及频谱-VC++ based digital communication system simulation, implementation of the various aspects of digital communication can be a part of the observed waveform and spectrum
