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:
“I would rather be exposed to the inconveniences attending too much liberty than those attending too small a degree of it.”
—Thomas Jefferson (1743–1826)
“There is always a degree of ridicule that attends a disappointment, though often very unjustly, if the expectation was reasonably grounded; however, it is certainly most prudent not to communicate, prematurely, one’s hopes or one’s fears.”

“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.”
