Q. |
Use mason’s gain formula to find the transfer function of the following signal flow graph: |
A. | abcd+efg/1-cd-fg-cdfg |
B. | acdfg+bcefg/1-cd-fg-cdfg |
C. | abef+bcd/1-cd-fg-cdfg |
D. | adcdefg/1-cd-fg-cdfg |
Answer» B. acdfg+bcefg/1-cd-fg-cdfg | |
Explanation: using mason’s gain formula transfer function from signal flow graph can be calculated which relates the forward path gain to the various paths and loops. |
