模拟语音信号的加噪去噪实验研究

Study based on experiments to deal noise of analog sound signals

基于虚拟仪器平台,利用数据采集卡获取的信号来模拟语音信号,通过不同信号的采集及合成,完成模拟信号的加噪处理。语音信号的去噪处理则是利用LabVIEW提供的滤波器完成的。

Based on the platform of virtual instrument,we can acquire the analog sound signals by using the data acquisition card.The noise-adding of the analog sound signals can be done through different signals' acquisition and synthesis.Under the LabVIEW,the analog sound signals' noise signal can be removed.
