Homework Statement


Find the transfer function of an RLC circuilt and the magnitude. (All the impedances are in series) and the Vo is in the R. Vi is the source voltage.


Homework Equations





The Attempt at a Solution



So transfer function of the circuit => Vo/Vi = R/ (sL+1/sC + R)

solving all this and assuming that R=C=L=1
I get

H(s)= s/(s^2+1+s)

H(ω)= jω/(j^2*ω^2+1+j*ω)

For the magnitud I get :

|H(ω)|= ω/sqr(ω^4+ω^2+1)

But I think the magnitude is wrong, please help.

Remember that j^2 = -1
