Abstract
A process for obtaining the periodic component in a data vector of data taken of a sensed property of an element driven by one or more rotary components over several rotations. The procedure comprises first forming the data vector asynchronously with respect to rotation of said one or more rotary components. A series of marker signals representing the rotation of the one or more rotary components is also established. From these the periodic component of data in said data vector is determined as a function of the data in the data vector and the marker signals.
Claims4
A process for obtaining the periodic component in a data vector of data taken of a sensed property of a rotated unit under test over several rotations comprising the steps of:
- forming said data vector asynchronously with respect to rotation of said rotated unit under test;
- receiving marker signals representing the rotation of the rotated unit under test;
- determining the periodic component of data in said data vector as a function of the data in said data vector and said marker signals;
- and
- determining the non-periodic component of data in said data vector by removing said periodic component of data from said data vector.
