Hi,
How balanced Pi attenuator configuration be changed to unbalanced PI
attenuator configuration?

Thanks and Regards

Hi,
RFSim99 tools plots the S-parameters vs Frequency.
I am not able to understand which S-parameters (S11,S12,S21,S22)
corresponds to filter frequency characteristics.
S parameters reflect the transmission and reflection co-oefficient how
is its mapping to filter characteristics.

How many sections do you expect to cascade? For only 2 or 3, it's easy 
to write the loop equations as a function of s. (Don't forget source ans 
load impedances.)

A great tool for this is pencil and paper. Write down the "s"
equations (these come from Laplace transforms) for the proportional
and the integral parts, sum them and then evaluate the sum at s ==
j*omega.

Hi,
Is there any tool which gives the frequency response of the PI filter
(where I can enter the resistance and Capacitor values).


Thanks and Regards
