Homework Statement
the question can be ignored - it involves laplace and Z transforms of RLC ckts.
Code:
Vc(s) = 0.2
-----------------
s^2 + 0.2s + 1
find the partial fraction equivalent such that it is :
Code:
-j(0.1005) + j (0.1005)
-------------- ------------------
s + 0.1-(0.995) s + 0.1 + j(0.995)
Homework Equations
none
The Attempt at a Solution
Code:
0.2 A B
--------------- = --------------------- + -------------------
s^2 + 0.25 + 1 s + (0.1 - j(0.995))) s + (0.1 + j(0.995))
0.2 = A(s + 0.1 + j(0.995)) + B(s + (0.1 - j0.995))
0.2 = As + A(0.1 + j(0.995)) + Bs + B(0.1 - j0.995)
so As + Bs = 0
or (A + B) = 0
or A = -B
so
0.2 = j(0.995A) - j(0.995B)
somethings not right - if i evaluate this I don't get anywhere near the answer
