$\frac{{C\left( s \right)}}{{R\left( s \right)}} = \frac{K}{{\left( {s + 1} \right)\left( {s + 2} \right)}}$

TuteeHUB · Answer

$\frac{{C\left( s \right)}}{{R\left( s \right)}} = \frac{{ - K}}{{\left( {s + 1} \right)\left( {s + 2} \right) + K}}$

TuteeHUB · Answer

$\frac{{C\left( s \right)}}{{R\left( s \right)}} = \frac{K}{{\left( {s + 1} \right)\left( {s + 2} \right) + K}}$

TuteeHUB · Answer

$\frac{{C\left( s \right)}}{{R\left( s \right)}} = \frac{K}{{\left( {s + 1} \right)\left( {s + 2} \right) - K}}$
