ECE 325 - FINAL QUIZ

If the first-order system parameter describes a response's speed, then the second-order system describes what of a response?

• velocity

• degree

• form

• error

It is described as the time for 𝒆^(−𝒂𝒕) to decay to 37% of its initial value

• Time Response

• Time Constant

• Settling Time

• Rise Time

It is a second-order system that oscillates its ωn without any amplitude decay.

• Undamped System

• Underdamped System

• Critically damped System

• Overdamped System

It is a dimensionless quantity that compares the envelope's exponential decay frequency to the natural frequency during a transient response.

• ς

• ωn

• , ωd

• a

In a second-order system, a damping ratio with a low value results in what kind of oscillation in the response?

• constant oscillation

• low oscillation

• more oscillation

• no oscillation

It s the amount that the waveform overshoots the final value at the peak time.

• Ts

• Tp

• Tr

• %OS

It is the significant parameter used to describe the transient response specification of a first-order system.

• exponential frequency

• natural frequency

• exponential speed

• natural speed

The time response of a system with a transfer function G(s)=(s+5)/(s+4) is:

• c(t)=A+B e^(4t)

• c(t)=A+B e^(-4t)
