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 背景知識數(shù)字信號處理（Digital Signal Processing,簡稱DSP）是一門設(shè)計許多學(xué)科而又廣泛應(yīng)用于許多領(lǐng)域的新興學(xué)科。DSP有兩種含義：Digital Signal Processing（數(shù)字信號處理）、Digital Signal Processor（數(shù)字信號處理器）。我們常說的DSP指的是數(shù)字信號處理器。數(shù)字信號處理器是一種適合完成數(shù)字信號處理運算的處理器。20世紀60年代以來，隨著
