For a signal y(t), the Laplace transform is:
Y(s) = 1/[s(s-1)]
What is the final value of the signal?
Solution:
For a unit step input, a system with a closed-loop transfer function (CLTF) G(s) = 20/(s^2 + 2s + 5) has a steady-state output of:
Solution:
Calculate the time constant if one of the poles of a transfer function is at -5, provided the system is stable.
Solution:
If G(s) is a stable transfer function, then F(s) = 1/G(s) is:
Solution:
If a transfer function with 3 zeroes of a unity-feedback system maps to a contour that encircles the point (-1, 0) twice, then what is the number of poles in the transfer function?
Solution:
Compared to an uncompensated system, how does a system compensated with a PD controller typically behave?
Solution:
A linear time-invariant system is defined with an impulse response of e2t, where t>0. With initial conditions as zero and the input as e3t, what is the output for t>0?
Solution:
The response of an LCR circuit to a step input is critically damped if and only if the transfer function has:
