\(V(s)=\frac{8 s^3+139 s^2+774 s+1471}{s^4+12 s^3+77 s^2+296 s+464}\)
ANSWER:Step 1 of 4
Given ,,
We need to find the inverse Laplace transform.So we will find the partial expression first. According to given problem partial expression are done by MATLAB as below,
>> num= [8 139 774 1471] ;
den= [1 12 77 296 464] ;
[ r , p ] = residue (num, den)
r =
3.0000 - 6.0000i
3.0000 + 6.0000i
2.0000 + 0.0000i
3.0000 + 0.0000i
P =
- 2.0000 + 5.0000i
- 2.0000 - 5.0000i
- 4.0000 + 0.0000i
- 4.0000 + 0.0000i
