Digital Watch
In a digital watch the mechanical parts of the traditional mechanical wristwatch have been replaced by a vibrating quartz crystal to keep time. The vibrating quartz crystal is controlled by
minute electronic circuits. One of the advantages of quartz is that it
is very stable. The artificial quartz crystals used in digital watches
are designed to vibrate up to 32,768 cycles per second when the
current from a battery is passed through them.
These vibrations produce electric pulses. As the pulses travel
through the electronic circuits of the microchip, their rate is gradually halved. The result is a pulse rate of one per second.
Each one-second pulse triggers the microchip to send signals to
the liquid crystal display to advance the numerals by one second.
The pulses are also used to control different functions. Such a digital watch can show the day and date; it can have an alarm and a reminder and can act as a stopwatch with an accuracy of 1/100th
second.
