Dynamic Range

Dynamic range, abbreviated DR or DNR, is the ratio between the largest and smallest possible values of a changeable quantity, such as in signals like sound and light. It is measured as a ratio, or as a base-10 (decibel) or base-2 (doublings, bits or stops) logarithmic value.

Famous quotes containing the words range and/or dynamic:

    Jane Addams, founder of Hull House, once asked, “How shall we respond to the dreams of youth?” It is a dazzling and elegant question, a question that demands an answer—a range of answers, really, spiraling outward in widening circles.
    William Ayers, U.S. author. To Teach: The Journey of a Teacher, ch. 7 (1993)

    Knowledge about life is one thing; effective occupation of a place in life, with its dynamic currents passing through your being, is another.
    William James (1842–1910)
