The force plate measurement system unavoidably introduces noise in the output signals. The noise in the center of pressure (COP) signal is the propagation noise arises from the combination of the components used to compute it. A framework to analyze the random error in COP signals is introduced based on the “Guide to the Expression of Uncertainty of Measurement” (GUM) approach.
