Thanks for using Brainmass.

Solutions:

7. From the transfer function, get the system poles:

The poles are:

Answer: Since there are no roots on the right s-plane (no positive roots) but there are roots on the imaginary axis, therefore the system is marginally stable

8. For this problem, let's substitute the s variable to jω. ...
