title: which type of filter can we use to remove gravity from an accelerometer
body: <p>Context: </p>
  
  <p>i have an dispositif which contains an accelerometer. Due this acceleromter, i obtain acceleration in 3 axis . if my dispositif is stable, it gives me : 
   accel x: 0;
   accel y: 0;
   accel z: 9,8 ( gravity)</p>
  
  <p>when we move the Dispositif, the gravity spreads in 3 axis . As far as we know , tha acceleration is the sum bewtenn dynamic acceleration (due mouvement) and static acceleration (gravity). </p>
  
  <p>my goal is to remove static acceleration (gravity). </p>
  
  <p>My question can i use high pass filter ? or exist other tpe of filter which can remove the gravity?</p>
  
  <p>Thanks in advance</p>
