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 ...
