Assignment 2: Design of Digital FiltersIntroductionIn this exercise you are required to design several digital filters using Matlab. Each student will be given adifferent set of design specifications. For this assessment you must submit the filter coefficients for each ofthe designed filters.Your individual set of design specifications can be found in the file :DFSA\restricted\xxxxxxx\assignment2_xxxxxx.htmWhere xxxxxxx is your UOB username.Note that all 4 filters will have the same values of sampling and pass-band frequencies. The 2 FIR filterswill have the same filter order, and the 2 IIR filters will have the same order.Submission procedureYou should submit your solution as a single Matlab .mat file to the following address:DFSA\restricted\xxxxxxx\submit\assignment2_xxxx.matWhere xxxxxx is your UOB username.The .mat file should contain 6 row vectorDigital Filters作业代写、代做IIR filters作业、代写Matlab实验作业、Matlab编程语言作s b1, b2, a3, b3, a4, b4 specifying the coefficients (numeratorbx and denominator ax) for each of the 4 filters. Since filters 1 and 2 are FIR, their denominators a1 anda2 will be 1 and need not be specified.You should use the Matlab save command to generate this file. Do not try to cut and paste coefficientvalues, as this may not give sufficient precision and may result in unstable filters and poor marks.Please do not include any other data in your .mat file. See Matlab help on the save command for savingindividual variables.The following script can be used to check your .mat file:load(‘filename’);freqz(b1, 1);pausefreqz(b2, 1);pausefreqz(b3, a3);pausefreqz(b4, a4);pauseThe assignment will be marked out of 20 with 5 marks for each filter.Note: Failure to follow these instructions may result in loss of marks for the assignment.转自：http://www.6daixie.com/contents/12/4576.html
