Draw the equivalent Signal Flow Graphs of the following Block Diagrams: Problem 1: X(s) + Σ Y(s) 2 → H,(S) H (S)

Problem 2: H,(s) X(s) + Y(s) H,(s) Σ H,(s) Σ H,(s) Η(s)

Problem 3: X(s) + + Y/s) H,(s) Σ » H,(s) Σ (s)*H - H,(s) Problem 4: H_(s) X(s) + Y(s) +A Σ h+ H,(s) H,(s) ༢ — (s)*H + བ་ བར་ ། +A H (s) ༽H,(༦) - (
