Question

TuteeHUB · Accepted Answer

${x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} - \frac{{d{x_1}}}{{dt}} - {x_1} - 1$

TuteeHUB · Answer

${x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} + \frac{{d{x_1}}}{{dt}} - {x_1} - 1$

TuteeHUB · Answer

${x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} + \frac{{d{x_1}}}{{dt}} - {x_1}$

TuteeHUB · Answer

${x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} + \frac{{d{x_1}}}{{dt}} - {x_1} + 1$

1.	The expression for x3 from the following signal flow graph is:
A.	\({x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} + \frac{{d{x_1}}}{{dt}} - {x_1} - 1\)
B.	\({x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} + \frac{{d{x_1}}}{{dt}} - {x_1}\)
C.	\({x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} - \frac{{d{x_1}}}{{dt}} - {x_1} - 1\)
D.	\({x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} + \frac{{d{x_1}}}{{dt}} - {x_1} + 1\)
Answer» C. \({x_3} = \frac{{{d^2}{x_2}}}{{d{t^2}}} - \frac{{d{x_1}}}{{dt}} - {x_1} - 1\)
