Calculate noise in active filters?

[Elektro]

How do I calculate output noise in active OP amp filters?

I would like to calculate the theoretical output noise of my active
bandpass filter.

Could I use Switcher CAD III from Linear Technology to simulate noise?

Yep. Unfortunately the noise model of the OpAmp may NOT be properly
characterized.
