| May 12, 2019 at 18:48 | comment | added | jonk | @noorav I already did all this in a three stage RC. So look here for a complete analysis process that you can follow for just two stages, as well. I could repost it here, but with just two stages. But can you use it to do this yourself? | |

| May 12, 2019 at 12:17 | comment | added | Marcus Müller | yep, that's the formula for the unloaded voltage divider. But: assuming you can just cascade RC filters like that is a mistake we've all been through at least once. I sympathize! I think in this situation: try with a star-triangle transform, simplify a bit and then you have a single, different voltage divider that you can analyze. | |
