    77This circuit produces a pulse burst in response to an input pulse.  The
    8 output-pulse period, the length of burst, and the time delay between the input
    9 pulse and the start of the burst are programmable.  This circuit is
     8output-pulse period, the length of the burst, and the time delay between the
     9input pulse and the start of the burst are programmable.  This circuit is
    1010non-retriggerable in the sense that any additional input pulses that occur
    1111during the output-pulse burst are ignored.

    1618The input pulse is called ``ShakerClk`` because of the application from which
    17 this example was taken.  The application was to acquire 6000 x-ray images, at
    18 2000 Hz, of an object being shaken at 60 Hz.
