An illustration of one way the Potapov product and the singular function can be separated for Example 2 in Section  7.2 . We notice that some of the parallel delays can be commuted with a beamsplitter, forming the network in (a). The node labeled \(x_{0}\) can then be eliminated, forming the network in (b) which now has a 3-input 3-output unitary component denoted by U.
