standard frequency and time signals
11Frequency divider — A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, fin, and generates an output signal of a frequency: where n is an integer. Phase locked loop frequency synthesizers… …
12time perception — Introduction experience or awareness of the passage of time. The human experience of change is complex. One primary element clearly is that of a succession of events, but distinguishable events are separated by more or less lengthy… …
13Time-domain reflectometer — A time domain reflectometer (TDR) is an electronic instrument used to characterize and locate faults in metallic cables (for example, twisted wire pairs, coaxial cables). The equivalent device for optical fiber is an optical time domain… …
14Time-division multiplexing — (TDM) is a type of digital or (rarely) analog multiplexing in which two or more signals or bit streams are transferred apparently simultaneously as sub channels in one communication channel, but are physically taking turns on the channel. The… …
15Time and frequency transfer — describes mechanisms for comparing measurements of time and frequency from one location to another. The technique is commonly used for creating and distributing standard time scales such as International Atomic Time (TAI).Examples of time and… …
16Time dilation — This article is about a concept in physics. For the concept in sociology, see time displacement. In the theory of relativity, time dilation is an observed difference of elapsed time between two events as measured by observers either moving… …
17Standard time and frequency signal service — The Standard Time and Frequency Signal (STFS) is a service available in the United States (centered at 10.000MHz? .jg) which provides standard time and frequency signals, broadcast on very precise carrier frequencies by the U.S. Naval Observatory …
