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:
“Continual success in obtaining those things which a man from time to time desireth, that is to say, continual prospering, is that men call FELICITY; I mean Felicity of this life. For there is no such thing as perpetual Tranquillity of mind, while we live here; because Life it self is but Motion, and can never be without Desire, nor without Faeroe, no more than without Sense.”
—Thomas Hobbes (1579–1688)
“While you are divided from us by geographical lines, which are imaginary, and by a language which is not the same, you have not come to an alien people or land. In the realm of the heart, in the domain of the mind, there are no geographical lines dividing the nations.”
—Anna Howard Shaw (1847–1919)
