yes! but also keep in mind that 1/s is never 0 for any finite s, so even at high frequencies the error resulting from random noise is never zero, it's just strongly attenuated

That's right but "the Bode plot of an integrator is a line with a -20 dB/decade slope" doesn't really roll off the tongue ;)

it's implicit in this comment by kens though:

> if you buy a commercial-grade gyroscope for [us]$10, it will have a random walk error of several º/√h. So after summing the errors for an hour, you're left with several degrees of random error, which is bad. If you spend [us]$100,000 on a navigation-grade gyroscope, you'll get a random walk error < 0.002º/√h, which is much better.

if the slope was anything else, the unit of °/√h wouldn't make sense; it would have to be °/h or °/∛h or something. similarly for noise figures given in nanovolts/√Hz
