+====== Impulse ======
+When calculating impulse, the first step is to break the signal into two signals which only contain positive or negative values.
+Note that this script makes use of the [[Visual3D:Documentation:Pipeline:Expressions:Expressions_Overview#CURRENT_SIGNAL|Current_Signal]] function within Evaluate Expression.
