IIR滤波器设计
现有一个信号:x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的:
低通滤波器,滤除cos(2*π*n/3) 的成分,即想保留的成分为1+cos(π*n/4)
高通滤波器,滤除1+cos(π*n/4) 的成分,即想保留的成分为cos(2*π*n/3)
带通滤波器,滤除1+cos(2*π*n/3) 的成分,即想保留的成分为cos(π*n/4)
带阻滤波器,滤除cos(π*n/4) 的成分,即想保留的成分为1+cos(2*π*n/3)
1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器;画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。
(an existing signal : x (n) = a cos (* n/4) cos (2** n/3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2** n/3) the ingredients that want to retain an element of a cos (* n/4) high-pass filter, a filter cos (* n/4) components, namely to retain the element of cos (2** n/3) band-pass filter , a filter cos (2** n/3) components, namely to retain the element of cos (* n/4) band stop filter, the filter cos (* n/4) components, namely to retain the ingredients for a cos ( 2** n/3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).)

DCT_IDCT
to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression
for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution
now compare our special 8X8 functions with the internal general functions
use this code:
A = int32(100*rand(8,8))
tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc
tic for i = 1 : 1000 idct2(dct2(A)) end toc
i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)
