31Frequency 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… …
32Frequency averaging — In telecommunication, the term frequency averaging has the following meanings: #The process by which the relative phases of precision clocks are compared for the purpose of defining a single time standard. #A process in which network… …
33Frequency mixer — This article is about non linear mixing operating in the frequency domain. For other types of mixers, see electronic mixer. Frequency Mixer Symbol. In electronics a mixer or frequency mixer is a nonlinear electrical circuit that creates new… …
34Frequency changer — A frequency changer or frequency converter is an electronic device that converts alternating current (AC) of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to… …
35Standard error (statistics) — For a value that is sampled with an unbiased normally distributed error, the above depicts the proportion of samples that would fall between 0, 1, 2, and 3 standard deviations above and below the actual value. The standard error is the standard… …

37Frequency frogging — In telecommunication, the term frequency frogging has the following meanings: 1. The interchanging of the frequencies of carrier channels to accomplish specific purposes, such as to prevent feedback and oscillation, to reduce crosstalk, and to… …
38Frequency Shift Keying — Bildung eines binären FSK Signals. Oben: Quelldaten als eine Folge von logisch 1 und logisch 0. Mitte: Unmodulierte Trägerfrequenz Unten: Moduliertes FSK Signal. Die Frequenzumtastung (englisch Frequency Shift Keying, FSK) ist eine… …
39Frequency assignment authority — In telecommunication, frequency assignment authority is the power granted an administration, or its designated or delegated leader or agency via treaty or law, to specify frequencies, or frequency bands, in the electromagnetic spectrum for use in …
40Frequency sharing — In telecommunication, frequency sharing is the assignment to or use of the same radio frequency by two or more stations that are separated geographically or that use the frequency at different times. Frequency sharing reduces the potential for… …
