In telecommunication, the term degree of start-stop distortion has the following meanings:
- In asynchronous data transmission, the ratio of (a) the absolute value of the maximum measured difference between the actual and theoretical intervals separating any significant instant of modulation (or demodulation) from the significant instant of the start element immediately preceding it to (b) the unit interval.
- The highest absolute value of individual distortion affecting the significant instants of a start-stop modulation.
The degree of distortion of a start-stop modulation (or demodulation) is usually expressed as a percentage. Distinction can be made between the degree of late (positive) distortion and the degree of early (negative) distortion.
Famous quotes containing the words degree of, degree and/or distortion:
“A certain degree of fear produces the same effects as rashness.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“One who shows signs of mental aberration is, inevitably, perhaps, but cruelly, shut off from familiar, thoughtless intercourse, partly excommunicated; his isolation is unwittingly proclaimed to him on every countenance by curiosity, indifference, aversion, or pity, and in so far as he is human enough to need free and equal communication and feel the lack of it, he suffers pain and loss of a kind and degree which others can only faintly imagine, and for the most part ignore.”
—Charles Horton Cooley (1864–1929)
“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)
