Question
Which of the options is an equivalent representation of the signal flow graph shown here?
Correct answer
(C) [figure]
Solution
Label the nodes of the given graph from left to right: input node , node (after the first unity branch), node (after branch ), node (after branch ) and the output node (after the last unity branch).From the graph:
- goes from to , goes from to ,
- goes back from to (upper arc),
- goes back from to (lower arc).

AI-powered practice· Unlimited practice on eligible plans
- PYQs with solutions
- Attempt available previous-year questions, then compare your reasoning with the worked solution. Coverage varies by stream.
- Practice that adapts
- Choose a topic, work on weaker areas and bookmark questions to revisit. Your attempts feed your progress tracking.
- AI doubt support
- Ask follow-up questions about a step or concept while practising, instead of stopping at the final answer.
Unlimited practice is available on eligible plans. Free practice and AI usage have limits; check the current plan allowances before choosing.
