语音信号的频谱分析 利用FIR数字滤波器对语音信号进行滤波 语音信号处理初步-回声估计和回声消除 数字图像处理算法初步-Spectral analysis of speech signal Using FIR digital filter to filter the speech signal Processing of speech signal initial echo estimation and echo cancellation Digital image pr

非常适合计算机视觉方面的研究使用,窗函数法设计一个数字带通FIR滤波器，计算目标和海洋回波的功率谱密度。- Very suitable for the study using computer vision, A window function design FIR digital band-pass filter, Calculating a target and ocean echo power spectral density.

回声消除系统使用自适应滤波器模拟回声信道，自适应滤波器的阶数对回声消除效果具有重要的影响，合适的阶数可以提高回声消除效果。通过回声消除仿真对比实验显示，本算法的滤波器失准系数低于 NLMS、PNLMS 算法。-The echo cancellation system uses an adaptive filter to simulate the echo channel. The order of the adaptive filter has an important effect on th
