PI Filter Components

[troberts]

I have the PI Filter Components. I am interested in uderstanding the requency response.
of my circuit. Is there a calculator that can do this?

Thanks,

Tom

If you google it there are several.

Yes, But the calculators will calculate the values of the Inductors and capacitors I already have.

I need to go backwards..

I think you mean you want to know what the frequency response is of the parts you already have. If so use this one.

But...... You also need to know the input and output impedance to see how it will really work. This one gives you the response with 50 ohm input and output impedance.

Be a little careful with this site it will want to change your browser settings. Just close it after you are done.
