Usefulness of Allan deviation with DC signals
This is a follow-up question to Allan deviation to determine averaging time
I was under the impression that with DC signals I couldn't capture or average a signal forever to get better SNR, because of ...

Allan deviation to determine averaging time
Thanks in advance for the help. I don't post on here often, so I hope I can convey my question properly.
I think I understand what the Allan deviation (same as IEEE Allan variance?) does. You take a ...

Averaging data from 2 sensors
Suppose we take a reading of a single rotating axis using 2 identical sensors. Intuitively, I think that averaging the outputs of both sensors will yield a less noisy result. But what if sensor A has ...

Bias instability in Gyroscopes : AVER / ADEV
I am attempting to implement allan variance to determine the amount of bias that is shown in my IMU's gyroscope ( BMI160 ). I am doing this with the following formula, that was captured in the ...

How to interpret Allan Deviation plot for gyroscope?
Regions with different slopes correspond to different types of noises in Allan Deviation plot of a steady gyroscope at steady temperature.
My doubts are:
What is significance of x axis in this plot, ...

What determines the accuracy of the phase result in a DFT bin?
What are the factors that affect the accuracy and precision for the phase that is given by the DFT?
Just thinking medium-hard about this, it occurs to me that it must have something to do with the ...
