A first order system will be faster when the dominant pole:

• is closer to the imaginary axis

• further away from the imaginary axis

The overshoot in a 2nd order system can be decreased:

• by increasing beta

• by decreasing beta

An unwinding media roll in a printer is an example of:

• a non-linear time invariant system

• a linear time variant system

The effect of a delay is visible in:

• the Bode amplitude plot

• the Bode phase plot

When the mass of a mass-spring system is increased, the resonance frequency

• increases

• decreases

Increasing the proportional gain in a feedback system, yields:

• a better disturbance suppression

• a disturbance suppression reduction

A biased differentiator

• does not have any poles

• does not have any zeros

A system is unstable, when the system’s phase is -180° while the amplitude is:

• higher than 0dB

• lower than 0dB

The Nyquist plot of a differentiator

• starts in the origin (at w=0)

• ends in the origin (at w=inf)

Looking to the Nyquist plot of a stable system, wat must be the location of the -1 point when travelling from w=0 to w=inf?

• -1 must be at the right side of the Nyquist plot

• -1 must be at the left side of the Nyquist plot
