摘要
本文从矩阵理论的角度出发,分析数字信号及其处理,研究了离散傅立叶变换和数字滤波器的矩阵表示,通过分析得出,矩阵理论是"数字信号处理"课程最基础的数学理论,向量和矩阵能够更有效地表达数字信号及其处理,更有利于数字信号的分析。最后结合Matlab编程语言,给出了数字信号及其处理的矩阵表示和编程方法示例。
This paper analyzes digital signal processing using matrix theory and studies the representation of DFT (Discrete Fourier Transform ) and digital filter using matrix (vector) form. Matrix theory is the mathematic fundamental of Digital Signal Processing course. The representation of digital signal using matrix (vector) form is more efficient for digital signal analysis and programming design. In the end, the representation of digital signal and its' processing is designed using Matlab.
