## Homework Statement

Determine the T-network equivalent of the ∏ (Pi) network shown in the Figure?

## Homework Equations

I started working on this question and don't know if I am heading in the right direction.

The impedances of the T network (Z1, Z2, Z3) can be found from the impedances of the equivalent pi network with the following equations:

Z1= ( Za x Zb ) / ( Za+ Zb + Zc )

Z2= ( Zb x Zc ) / ( Za+ Zb +Zc )

Z3 = ( Za x ZB ) / ( Za + Zb + Zc )

And then we can use our details:

C1 = Za

L1 = Zc

C2 = Zb

Z1 = (-j20 x j10 ) / (-j20+j10-j20)= -200j^2 / -30j = j6.67

Z2 = (-j20 x j10 ) / ( -j20+j10-j20) = -200j^2 / -30j = j6.67

Z3 = ((-j20 ) x (-20j )) / (-20j+ 10j -20j) = 400j^2 / -j30 = -j13.333

and now we come out with equivalent T -network. At least I hope!
