A frequency standard is a stable electronic oscillator oscillator used for frequency calibration or reference. A frequency standard generates a fundamental frequency with a high degree of accuracy and precision . Harmonics of this fundamental frequency are used to provide reference points. Since time is the reciprocal of frequency, it is relatively easy to derive a time standard from a frequency standard. A standard clock comprises a frequency standard, a device to count off the cycles of the oscillation emitted by the frequency standard, and a means of displaying or outputting the result. Frequency standards in a telecommunications network network or Telecommunications facility facility are sometimes administratively designated as primary or secondary . The terms primary and secondary , as used in this context, should not be confused with the respective technical meanings of these words in the discipline of precise time and frequency. Frequency reference A frequency reference is an instrument used for providing a stable frequency of some kind. There are different sorts of frequency references, acoustics acoustic ones such as tuning fork s but also electrical ones that emit a signal of a certain frequency a frequency standard . Among the most stable frequency references in the world are caesium standard s, including Caesium fountain caesium fountains , and hydrogen maser s. Caesium standards are widely recognized as having better long term stability, whereas hydrogen masers can attain superior short term performance therefore, several national Measurement standards laboratory standards laboratories use ensembles of caesium standards and hydrogen masers in order to combine the best attributes of both.

Digital frequency is the analogue for discrete signal s as frequency is to continuous signal s. Since a discrete signal is a sequence merely a series of symbols typically, numbers it contains no direct information as to determine the frequency of the corresponding continuous signal. Just like in frequency , a digital frequency can have values in degree angle degree s or radian s. However, it is common to represent a digital frequency that has been normalized to either the Nyquist frequency or the sampling frequency . It is therefore very important to specify the frequency range. The following frequency ranges assume a signal has been properly sampled by satisfying the Nyquist Shannon sampling theorem . Each one of these could use a sample plot with the range clearly marked and using some easily understandable signal like a low pass filter Standard ranges The values of a valid signal is in the range of math left frac F s 2 , frac F s 2 right math hertz. Likewise for radians, values of digital frequency are in the range math left frac omega s 2 , frac omega s 2 right math radians. Normalized ranges The normalized hertz range is the hertz range divided by the sampling frequency. A valid signal is on math left frac 1 2 , frac 1 2 right math cycles per sample. Instead, the normalizing frequency could be the nyquist frequency, which puts a valid signal on math left 1, 1 right math cycles per sample. For radians, normalized frequencies are in the range math left pi, pi right math , equivalent to half a cycle per sample. Clearly a frequency of just 0.1 is insufficient to describe the true frequency of the discrete signal . To remove the ambiguity, it is necessary to specify the range and what normalization frequency was used if applicable .
