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 Praveen

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. Clay

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.)

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. Regards Praveen
