In 1958, Oscilloquartz began their activity in atomic frequency standards.

The higher frequency standard would be able to handle much more data.

A simple electronic feedback loop can lock the repetition rate to a frequency standard.

Development of increasingly accurate frequency standards is underway.

They can be therefore used as frequency standards.

The signals, transmitted at 60 kHz, also provide a national frequency standard.

The transmitters use a primary frequency standard to derive the frequencies used.

But only last year, it was suggested that collisions between the chilled atoms might change the frequency standard by a small but significant amount.

In 1986, the frequency international standard of 457 kHz was adopted, and this remains the standard today.

Until recently, most mobile phone users have not been able to use the same phone across continents because of differing frequency standards.
