The simplest clock generation source is an oscillator (XO). The national frequency standards developed by NIST and other laboratories derive their resonance frequency from the cesium atom and typically use cesium fountain technology. to support not only SONET/SDH and Ethernet, but also high-definition video transmission.

In theory, the atom is a perfect “pendulum” whose oscillations are counted to measure a time interval. The principle underlying the atomic oscillator is that since all atoms of a specific element are identical, they should produce exactly the same frequency when they absorb or release energy. Modern oscillators use many different circuits and generate such outputs as sinusoidal, square, rectangular, sawtooth, and trapezoidal waveshapes. They generate signals from a few hertz to several gigahertz (10 9 hertz). The resonance frequency, fo, of an atomic oscillator is the difference between the two energy levels divided by Planck’s constant, h. Oscillators (wave generators) play a prominent role in the field of electronics. An electromagnetic field at a particular frequency can boost an atom from one energy level to a higher one, or an atom at a high energy level can drop to a lower level by emitting energy. An oscillator is a technical indicator that is used to help determine over bought/sold conditions or to. Oscillators are used, for example, to test electronic circuits. Oscillator Definition: Day Trading Terminology. The laws of quantum mechanics dictate that the energies of a bound system, such as an atom, have certain discrete values. An electroacoustical device used to generate SIGNALs with specific WAVEFORMs.

An oscillator circuit is usually made up of a. An oscillator that uses the quantized energy levels in atoms or molecules as the source of its resonance. Definition: An oscillator is an electronic circuit that generates an ac signal at the desired frequency.
