| Apr 6, 2023 at 0:07 | comment | added | Dan Boschen | Is the plot ADEV or AVAR (the vertical axis would be $\sigma^2$ is AVAR, and in either caes the horizontal axis is time in seconds ($\tau$) not frequency. If ADEV the line shown is going down at $1/\tau$ instead of $1/\sqrt{\tau}$ (The two are related as $ADEV = \sqrt{AVAR}$). When/if the noise is white the rms computation would match the ADEV computation (can you plot the noise plot on a log log scale? That should help with that comparison). Also the use of "Rate" in the horizontal axis for your averaging result is confusing as rate means frequency-- | |
