High Frequency Signals

Famous quotes containing the words high, frequency and/or signals:

    Who dreamed that beauty passes like a dream?
    For these red lips, with all their mournful pride,
    Mournful that no new wonder may betide,
    Troy passed away in one high funeral gleam,
    And Usna’s children died.
    William Butler Yeats (1865–1939)

    The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.
    Jean Marzollo (20th century)

    The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.
    Lawrence Kutner (20th century)
