How else would you describe what occurs other than 6dB/octave?
- badmintonbaseba 1y agoNotice how both dB and octave are ratios, but for some reason for frequency ratios we don't use bels or decibels. An octave is a ratio of 2, a bel is a ratio of 10.
- nayuki 1y agoFor frequency, a decade is a ratio of 10, akin to a bel. And in photography, a stop or an EV is a factor of 2, akin to an octave. https://en.wikipedia.org/wiki/Logarithmic_scale#Common_uses https://en.wikipedia.org/wiki/Logarithmic_scale#Common_uses
- cousin_it 1y agoFor a 6dB/octave lowpass filter, I would say power gain is inversely proportional to frequency squared (1/f^2). There's precedent for this notation, for example pink noise is known as both 3dB/octave and as 1/f.
