Hello, i got this circut http://img504.imageshack.us/my.php?image=circiutol5.jpg

First i shall decide Uin/Uut which i get to be R/(jwL + 1/(jwC) + RL+ R)

Then i have to find an expression for w0,
w = (RL/2L) + (RL(CL^0.5) + 2L)/(2L(CL^0.5))

And now to what i dont get, Find a method to decide L and RL if u know C and R
Im completely clueless

 

nvm this post, i have solved the problem
