  1. Gps is a planet wireless conductance system which is global and all - weather, gps can offer high precision time orientation information to infinite user, clock precision reachs 10 ? 6 magnitude 。 not only changes traditional time method of quartz crystal clock, but also replaces wireless shortwave and even more lowfrequency signal and tv signal whose overlay range is limited and low precision, offers advantage to geology field task, achieve automatization and high precision of seismic flow observation

    利用gps授時信號全方位、全天候、連續性、實時性和高精度的特點,以gps信號為基準來校準本地時鐘(晶體振蕩時鐘或原子鐘) ,將gps接收機輸出信號的長期穩定度和恆溫晶振的短期穩定度相結合,應用大規模可編程邏輯器件,設計和實現了由pc104控制的實時在線授時系統。
  2. The concept of " timing " in the article is not the clock in our ordinary living, but syntheses which is made up of some frequency source in the signal generator ( such as cs atom frequency standard, rb clock & high accuracy quartz crystal oscillator ) which produces the primary frequency, the matching input interface and the matching output interface and controlling circuit etc. for example, bits is a kind of timing equipment, which is used to control the timing of some functions

    本文論及的「時鐘」概念不是指日常生活中使用的鐘表,而是由產生基準頻率的信號發生器(如銫原子頻率標準、銣鐘及高精度石英晶體振蕩器等)中的某種頻率源以及相配套的輸入、輸出介面和控制電路等組成的一整套具有特定同步定時功能的綜合體。如bits就是一種時鐘設備,它提供用在通信系統中控制某些功能的定時的時間基準設備,時鐘提供的信號稱為基準信號、定時信號或同步信號。
  3. The adc aperture jitter must be minimal, and the sampling clock generated from a low phase - noise quartz crystal oscillator

    Adc的孔徑抖動必需盡可能的小,而且要使用低相位噪聲的石英晶體振蕩器作為采樣時鐘發生器。
