The flow graph shown in Figure is noncomputable; i.e., it is not possible to compute the output

Question:

The flow graph shown in Figure is noncomputable; i.e., it is not possible to compute the output using the difference equations represented by the flow graph because it contains a closed loop having no delay elements.

(a) Write the difference equations for the system of Figure, and from them, find the system function of the network.

(b) From the system function, obtain a flow graph that iscomputable.
