___________From which of the following transfer function can be obtained ?
Correct answer: A. Signal flow graph
- A. Signal flow graph
- B. Analogous table
- C. Output-input ratio
- D. Standard block system
- E. None of the above
Explanation
A signal-flow graph represents the relationships among system variables, and Mason’s gain formula can be used to obtain the transfer function from it. The output-input ratio is the definition of a transfer function, not the usual graphical method asked for here.
