State estimation

Low Pass filtering before does not make sense
EKF might be tool of choice
Store historical data in the Filter file locally in a ring buffer

K,H, phi can be variable to have more performance
Higher Gain =higher smoothing, also more delay
Kalman does the same as Low Pass Filter (just better) → substitute at some point

EKF intuition:
prior estimate + data → posterior estimate
read paper to Kalman filters from Livi

Big questions:
Can i first do a KF and later extend it to an EKF? (Livi was unsure)
My Kalman does not have just one variable, but multiple. how do they interact?
ChatGPT: Do them all independent, and maybe later linked?
