Need help with creating a measure to calculate roll rate
I was able to calculate them in Excel and have tried several measures in Power BI but no luck. For instance, to calculate 1-30 roll rate%: I divided 1-30 amount of current month by Current amount of previous month. Please refer to the screenshots to see the sample calculation. Also, I am attaching a table with sample dataset for reference.

LC Filter Calculator
An LC filter is a second-order filter circuit because it has both an inductor and a capacitor, whose impedance depends on the signal's frequency. As such, it reacts faster to a signal frequency and has twice the frequency slope (also known as frequency roll-off) in the Bode plot compared to a passive filter like RC or RL.. A low-pass LC filter circuit has an inductor …

Diameter of Rolls
Fig. 1.24 Position of pass vis-a-vis collars.. The number of collars in a roll set would always be (n + 1), where n is the number of passes in the roll set.As shown in Fig. 1.24 there are two passes (P 2) of Beam 125 in the roll, and then numbers of collars will be (2 + 1) i.e., three. If the collar protrudes beyond the boundary of the pass, then it is called as positive collar or a collar.

Is the roll-off gain of filters always -20 dB/dec?
$begingroup$ You have to look at all the poles and zeros of the filter. There is an academic technique to draw an approximate Bode plot based on the poles and zeros. In general, the slope of the simple low-pass filter response is 20dB per decade if there is only one reactive component. 40dB per decade if there are two reactive components, 60 if three, etc. Google …
