Figure 3

The block diagram with additional gain block used for the derivation to recast the smoother as a position estimator. Here the transfer function \(h(t)\) is modified to \(h^{\prime}(t)\) that assumes position, \(x_{e}(t)\) (units of metres), rather than voltage, \(v_{e}(t)\), as an input. As such the smoothed output, \(x_{s}(t)\), is similarly a position estimate.
