Time Domain

Time domain is the analysis of mathematical functions, physical signals or time series of economic or environmental data, with respect to time. In the time domain, the signal or function's value is known for all real numbers, for the case of continuous time, or at various separate instants in the case of discrete time. An oscilloscope is a tool commonly used to visualize real-world signals in the time domain. A time-domain graph shows how a signal changes with time, whereas a frequency-domain graph shows how much of the signal lies within each given frequency band over a range of frequencies.

Famous quotes containing the words time and/or domain:

    “Slow, slow, fresh fount, keep time with my salt tears;
    Yet slower yet, oh faintly gentle springs:
    List to the heavy part the music bears,
    “Woe weeps out her division when she sings.”
    Droop herbs and flowers;
    Fall grief in showers;
    “Our beauties are not ours”:
    Oh, I could still,
    Like melting snow upon some craggy hill,
    Drop, drop, drop, drop,
    Since nature’s pride is, now, a withered daffodil.”
    —Ben Jonson (1572–1637)

    “In the domain of art there is no light without heat.”
    —Victor Hugo (1802–1885)
