Question

For the transfer function $G\left(j\omega \right)=5+j\omega$, the corresponding Nyquist plot for positive frequency has the form

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

$G\left(j\omega \right)=5+j\omega$
$|G\left(j\omega \right)|=\sqrt{25+{\omega }^2}$
At $\omega =0$
$|G\left(0\right)|=\sqrt{25+0}=5$
At $\omega =\infty$
$|G\left(\infty \right)|=\infty$
