Digital Watches

A digital watch is a type of watch that bases its operation on a digital time base to generate the required frequency pulses (usually 1 Hz). A digital watch, like LED display watches, is a watch on the base of the digital frequency division and time.

The invention in 1956, the digital watch was a great revolution in the field of watch manufacturing because it got much cheaper and more accurate than mechanical watches operation.

To represent time, many digital watches use the seven LED, VFD or LCD segments to form each of the numbers, for example, the dual time digital watch. These watches also include other elements, to indicate whether the time is AM or PM in the afternoon tomorrow, and if the alarm is on. Digital watches can be much smaller, useful and inexpensive. For these reasons have been incorporated in most digital equipment. Many digital watches are used as alarm watches that have built-in radio.

The union with the mechanical watch, is removing all devices that were inside the box watches and were replaced by digital circuitry powered by a small battery and make direct reading time.

Because of the low price that have digital watches have already been imposed in many applications, and so most alarm watches are already digital, watches appliances, computers, mobile phones, cars, etc .. At the same time, many of the watches used are digital although in the field of watches the analog-digital quartz imposed.

Operation of a digital watch

Watch accuracy depends on time base, which may consist of an oscillator or an adapter on the baseline, it generates a periodic signal. The frequency divider is a digital circuit formed by a succession of counters for a frequency of 1 Hz, which allows show seconds. If you want to show tenths, the division could be 10 Hz. This often happens in the presentation, which can be mechanical or digital, where others were dividers separating the seconds, minutes and hours to present through some sort of screen.
