However, in other fields within electronics, we … 2014 · Trophy points. 2008 · 1. air or water molecules) are allowed to pass Larger particles (e. 12dB/octave (second-order) filters are better at keeping unwanted . It calculates components values of an high pass filter for a passive audio crossovers. So for example, a second-order filter would have a slope of -40dB/decade (-12dB/octave), a fourth-order filter would have a slope of -80dB/decade (-24dB . However, when I put it in the pole-zero plotter, I don’t get a nice 6dB/octave rolloff below the cutoff frequency – it all seems to happen at the high-frequency end. Keep in mind that an octave is the doubling of the frequency... "Q" is a measure of bandwidth.
