Hello again, I do know about the Kalman filter although it is not the one that I am going to use. I am getting the motion artefact from hand/arm vibration in the three dimensions (x,y,z). The filter that I will apply is the LMS (least mean square algorithm). One way is to use a 1-axis accelerometer to capture the motion (but I know how I can apply this since it is only one input) and the other way is to use all three axes (x,y,z) signals. Now, I can have 3 separated outputs - one for each dimension - or to combine the three input accelerometer signals to have only one input for the LMS adaptive filter. My problem is how can I combine those three signals to have only 1 input that will represent successfully the acceleration in all three directions. Thank you all for responding

Hello all, I have a question and I hope some of you might have an answer for me. I have to combine the 3-axes signals from a MEMS accelerometer in MATLAB so that I have the resulting signal as an input to several filters. Do you know how is that possible? I tried to find more information online but that was not successful. Whatever you know about this topic is useful so please do not hesitate to contact me. Eirini
