濾波器設(shè)計(jì)在數(shù)字信號(hào)處理中占有極其重要的地位，F(xiàn)IR數(shù)字濾波器和IIR濾波器是濾波器設(shè)計(jì)的重要組成部分。利用MATLAB信號(hào)處理工具箱可以快速有效地設(shè)計(jì)各種數(shù)字濾波器。課題基于MATLAB有噪音語(yǔ)音信號(hào)處理的設(shè)計(jì)與實(shí)現(xiàn)，綜合運(yùn)用數(shù)字信號(hào)處理的理論知識(shí)對(duì)加噪聲語(yǔ)音信號(hào)進(jìn)行時(shí)域、頻域分析和濾波。通過(guò)理論推導(dǎo)得出相應(yīng)結(jié)論，再利用 MATLAB 作為編程工具進(jìn)行計(jì)算機(jī)實(shí)現(xiàn)。在設(shè)計(jì)實(shí)現(xiàn)的過(guò)程中，使用窗函數(shù)法來(lái)設(shè)計(jì)FIR數(shù)字濾波器，用巴特沃斯、切比雪夫和雙線性變法設(shè)計(jì)IIR數(shù)字濾波器，并利用MATLAB 作為輔助工具完成設(shè)計(jì)中的計(jì)算與圖形的繪制。
