Parallel Interconnection

Figure 2.11 The parallel confguration.

 

A signal x (t) is routed to two (or more) systems, with this signal appearing as the input to all systems simultaneously and with equal strength. Block diagrams have the convention that signals going to more than one system are not split into pieces along the way. Two or more systems operate on x (t) and their outputs are added together to create the output y (t). Thus, y (t)= S₁ (x (t))+S₂ (x (t)), and the information in x (t) is processed separately by both systems.
