   * Computes the extrapolated COG or the [[https://www.sciencedirect.com/science/article/abs/pii/S0021929004001642?via%3Dihub|'extrapolated center of mass position']] using the following equation:
-  * xCoM = CoM + vCoM/sqrt(g/l) [3]
+  * xCoM = CoM + vCoM/sqrt(g/l)
+  * Expression requires three inputs:
+    * The first signal input is considered as the CoM position,
+    * second input is considered the velocity of the CoM,
+    * and the third input is the leg length of the model.
