"DSP using MATLAB" Example Example6.1

Today is the last day of 2016, see other Bo Friends are writing year-end summary, did this, did that, harvest full, and then look at themselves,

Stupefied for a year, did not know what to do, ashamed. Just received a phone call from a distant mother, my brother was an hour ago father, I

Code:

b = [1-3 11-27 18]; A = [16 12 2-4-1]; [B0, B, a] = Dir2cas (b, a)%-----------------------------------------%     START check%------------------------------ -----------Delta = impseq (0, 0, 7) format Longhcas = casfiltr (B0, B, A, delta) Hdir = Filter (B, A, delta)%----------------- --------------------------%       END check%--------------------------------------------    

Operation Result:

The structure diagram of the filter
