Step Response - Time Domain versus Frequency Domain

Time Domain versus Frequency Domain

Instead of frequency response, system performance may be specified in terms of parameters describing time-dependence of response. The step response can be described by the following quantities related to its time behavior,

  • overshoot
  • rise time
  • settling time
  • ringing

In the case of linear dynamic systems, much can be inferred about the system from these characteristics. Below the step response of a simple two-pole amplifier is presented, and some of these terms are illustrated.

Famous quotes containing the words time, domain and/or frequency:

    Then, Celia, let us reap our joys
    Ere Time such goodly fruit destroys.
    Thomas Carew (1589–1639)

    Without metaphor the handling of general concepts such as culture and civilization becomes impossible, and that of disease and disorder is the obvious one for the case in point. Is not crisis itself a concept we owe to Hippocrates? In the social and cultural domain no metaphor is more apt than the pathological one.
    Johan Huizinga (1872–1945)

    The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.
    Jean Marzollo (20th century)
