#### Example 2

For the filter

we obtain the output of

`residued`(§J.6) shown in Fig.6.4. In contrast to

`residuez`,

`residued`delays the IIR part until after the FIR part. In contrast to this result,

`residuez`returns

`r=[-24;16]`and

`f=[10;2]`, corresponding to the PFE

(7.22) |

in which the FIR and IIR parts have overlapping impulse responses.

See Sections J.5 and J.6 starting on page for
listings of `residuez`, `residued` and related
discussion.

B=[2 6 6 2]; A=[1 -2 1]; [r,p,f,m] = residued(B,A) % r = % 8 % 16 % % p = % 1 % 1 % % f = % 2 10 % % m = % 1 % 2 |
