- JohnBooty 5y agoYeah high pass / low pass have always seemed totally logical to me. At least once I knew what they meant. I suppose they're not 100% intuitive or self-explanatory, but I can't think of a better alternative.
- nyanpasu64 5y agoA second-order 12db/oct low-pass has a 12 db/oct high-cut, and some unknown (hopefully minimized) amount of ripple in the passband. There's an advantage in naming filters after the more "interesting" part of the spectral response (eg. a second-order 12 db/oct highcut) where you're doing the most sculpting of the spectrum, where different filter orders behave differently, and different designs have different levels of stopband leakage. Though on the other hand, there's some benefit in naming filters after what's passed.
