The acausal bond graph of system iNMP is
displayed in Figure 3.1 (on page ) and its label
file is listed in Section 3.1.1 (on page ).
The subsystems are listed in Section 3.1.2 (on page ).
This is a simple non-minimum phase system with an inverse-type
response. It is the standard fast negative and slow positive systems
in parallel. The corresponding inverse system iiNMP is
unstable.
