The degree of isochronous distortion, in data transmission, is the ratio of the absolute value of the maximum measured difference between the actual and the theoretical intervals separating any two significant instants of modulation (or demodulation), to the unit interval. These instants are not necessarily consecutive. This value is usually expressed as a percentage.
The result of the measurement should be qualified by an indication if the period, usually limited, of the observation. For a prolonged modulation (or demodulation), it will be appropriate to consider the probability that an assigned value of the degree of distortion will be exceeded.
Famous quotes containing the words degree of, degree and/or distortion:
“The world is burdened with young fogies. Old men with ossified minds are easily dealt with. But men who look young, act young and everlastingly harp on the fact that they are young, but who nevertheless think and act with a degree of caution that would be excessive in their grandfathers, are the curse of the world. Their very conservatism is secondhand, and they don’t know what they are conserving.”
—Robertson Davies (b. 1913)
“The degree to which the child-rearing professionals continue to be out of touch with reality is astounding. For example, a widely read manual on breast-feeding, devotes fewer than two pages to the working mother.”
—Sylvia Ann Hewitt (20th century)
“This is our fate: eight hundred years’ disaster,
crazily tangled like the Book of Kells:
the dream’s distortion and the land’s division,
the midnight raiders and the prison cells.”
—John Hewitt (b. 1907)
