A necessary and sufficient condition for multivaluedness in counter-cascaded systems has been recently presented, leading to reports of several systems exhibiting this property. This brief interprets a general information transmission system as a counter-cascaded system using Shannon's noisy-channel coding theorem, providing a sufficient but not necessary condition for single-valuedness.
Recently, a necessary and sufficient condition for multivaluedness to be implicitly exhibited by counter-cascaded systems was presented. Subsequently, several systems that exhibit multivaluedness were reported. This brief interprets a general information transmission system as a counter-cascaded system with Shannon's noisy-channel coding theorem, providing a sufficient but not necessary condition for single-valuedness.
