代码说明:

  (1) 自行设计产生两个离散序列信号,对其进行相加、乘及卷积运算。 (2) 利用filter命令求下面LTI系统的冲激响应: y(n)-0.7y(n-1)-0.6y(n-2) + y(n-3) = x(n) + 0.5x(n-1) (3) 画出系统的零极点图,判断系统的稳定性、因果性。 (4) 绘出系统的频响曲线。(lisan time signal analyse )

    FIR与IIR滤波器在DSP上的实现.   DSP是利用计算机或专用DSP处理器,以数字形式对信号进行采集、变换、滤波、估值、增强、压缩、识别等处理,以得到符合人们需要的信号形式。FIR(Finite Impulse Response)滤波器:有限长单位冲激响应滤波器,又称为非递归型滤波器,是数字信号处理系统中最基本的元件,它可以在保证任意幅频特性的同时具有严格的线性相频特性,同时其单位抽样响应是有限长的,因而滤波器是稳定的系统。(FIR and IIR filter is implemented on the DSP. DSP is the use of a computer or a dedicated DSP processor in digital form to the signal acquisition, conversion, filtering, valuation, enhancement, compression, recognition processing needs of the people to give signal form. FIR (Finite Impulse Response) filter: finite impulse response filter units, also known as non-recursive filters, digital signal processing system is the most basic element, it can guarantee any amplitude-frequency characteristics of both a strict linear phase-frequency characteristics, while the unit sampling response is of finite length, and thus the filter is stable system.)
