【正文】 處理已經(jīng)在通信等領(lǐng)域得到極為廣泛的應(yīng)用。數(shù)字信號(hào)處理器是一種適合完成數(shù)字信號(hào)處理運(yùn)算的處理器。DSP有兩種含義：Digital Signal Processing（數(shù)字信號(hào)處理）、Digital Signal Processor（數(shù)字信號(hào)處理器）。Abstract Digital signal processing analysis of digital signal processing course of the importance and features, in order to help the students to understand and grasp basic concepts, basic principles, basic analysis method, is put forward with the MATLAB for digital signal processing curriculum design, curriculum design and describes the specific methods, steps and content.The MATLAB language is widely used in engineering calculation and the numerical analysis in the field of advanced language, MATLAB powerful, easy to learn, a high efficiency, by the vast number of scientific workers39。通過(guò)數(shù)字信號(hào)處理課程的理論知識(shí)的綜合運(yùn)用，從實(shí)踐上初步實(shí)現(xiàn)對(duì)數(shù)字信號(hào)的處理。線性常系數(shù)差分方程求解是數(shù)字信號(hào)處理課程中常出現(xiàn)的課題，也是現(xiàn)代科學(xué)中值得深入研究的一個(gè)課題 本文介紹了線性常系數(shù)差分方程的基本概念，論述了其求解方法，并用MATLAB具體實(shí)現(xiàn)了線性常系數(shù)差分方程的求解。數(shù)字信號(hào)處理課程設(shè)計(jì)題目： 基于MATLAB的線性常系數(shù)差分方程求解 學(xué)院： 專業(yè)： 班級(jí)： 學(xué)號(hào)： 姓名： 指導(dǎo)教師： 目 錄摘 要 1第一章 背景 3 背景知識(shí) 3 《數(shù)字信號(hào)課程》特點(diǎn) 3 軟件介紹 4 MATLAB及數(shù)字信號(hào)處理 4第二章 設(shè)計(jì)目的及要求 6 設(shè)計(jì)目的 6 課程設(shè)計(jì)的內(nèi)容要求 7 設(shè)計(jì)要求 7第三章 設(shè)計(jì)任務(wù) 8第四章 設(shè)計(jì)原理 9 差分與差分方程 9 線性常系數(shù)差分方程 14 線性常系數(shù)差分方程的求解 15第五章 設(shè)計(jì)過(guò)程 16 用MATLAB求解差分方程 16第六章 設(shè)計(jì)代碼及結(jié)果 18 MATLAB源程序 18 程序運(yùn)行結(jié)果 20 比較結(jié)果總結(jié) 24第七章 收獲與體會(huì) 25致 謝 27參考文獻(xiàn) 28摘 要《數(shù)字信號(hào)處理》分析了數(shù)字信號(hào)處理課程的重要性及特點(diǎn)，為了幫助學(xué)生理解與掌握課程中的基本概念、基本原理、基本分析方法，提出了用MATLAB進(jìn)行數(shù)字信號(hào)處理課程設(shè)計(jì)的思路，并闡述了課程設(shè)計(jì)的具體方法、步驟和內(nèi)容。MATLAB語(yǔ)言是一種廣泛應(yīng)用于工程計(jì)算及數(shù)值分析領(lǐng)域的新型高級(jí)語(yǔ)言，MATLAB功能強(qiáng)大、簡(jiǎn)單易學(xué)、編成效率高，深受廣大科技工作者的喜愛(ài)，特別是MATLAB還具有信號(hào)分析工具箱，不需具備很強(qiáng)的編程能力，就可以很方便地進(jìn)行語(yǔ)音信號(hào)分析、處理和設(shè)計(jì)?；贛ATLAB的線性常系數(shù)差分方程求解主要是用MATLAB作為工具平臺(tái)，設(shè)計(jì)中涉及到差分方程的遞推求解以及用filter對(duì)系數(shù)向量的歸一化等等。關(guān)鍵字：MATLAB，線性常系數(shù)差分方程，數(shù)字信號(hào)處理。 favorite, especially the MATLAB also has a signal analysis toolbox, does not need to have very strong ability of programming, can be very convenient for the analysis of speech signal, processing and design.Linear constant coefficient differential equation is a digital signal processing program that often appear in the topic, as well as modern science and worthy of indepth study of a topicThis paper introduces the linear constant coefficient differential equation basic concept, discussed the solution method, and MATLAB the specific realization of linear constant coefficient difference equation.MATLAB based on the linear constant coefficient difference equation MATLAB is mainly used as a tool platform, design relate to differential equation recursive solution and the use of filter on the coefficient vector is normalized and so on. Through the course of digital signal processing theory, the integrated use of knowledge, from the practice of preliminary implementation of digital signal processing.Key words: MATLAB, Linear constant coefficient differential equation,Digital signal processing.第一章 背景 背景知識(shí)數(shù)字信號(hào)處理（Digital Signal Processing,簡(jiǎn)稱DSP）是一門(mén)設(shè)計(jì)許多學(xué)科而又廣泛應(yīng)用于許多領(lǐng)域的新興學(xué)科。我們常說(shuō)的DSP指
