If we reverse the directions of all branch transmittances and interchange the input and output in the flow graph, then the resulting structure is called as:
A. Direct form-I
B. Transposed form
C. Direct form-II
D. None of the mentioned
Answer:A
If we reverse the directions of all branch transmittances and interchange the input and output in the flow graph, then the resulting structure is called as:
A. Direct form-I B. Transposed form C. Direct form-II D. None of the mentioned
Explanation: According to the transposition or flow-graph reversal theorem, if we reverse the directions of all branch transmittances and interchange the input and output in the flow graph, then the system remains unchanged. The resulting structure is known as transposed structure or transposed form.
