[Education soft system] FIR DL : 0: 本次课程设计是用麦克风采集一段语音信号并对该语音信号进行滤波去噪处理。课程设计平台为MATLAB7.1。设计步骤为：首先采集一段语音信号并观察其频谱，然后设计一个汉明窗FIR滤波器，最后对该信号进行滤波。信号在进行滤波处理后，能够听到滤波后的语音信号和滤波前相比明显的变得清晰，基本达到了设计目的。-The curriculum design is a section of a microphone speech signal acquisition and filtering of the speech signal de-noising processing. Curriculum design platform MATLAB7.1. Design steps: First, a section of speech signal acquisition and to observe its spectrum, and then the design of a Hamming window FIR filter, the final filtering of the signal. Signal during the filtering processing, to hear the voice signal after filtering and filtering obvious ago became clear, the basic design to achieve the purpose.
