measured frequency
1Frequency counter — A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Since frequency is defined as the number of events of a particular sort occurring in a set period of time, measuring it is usually… …
2Frequency response — is the measure of any system s spectrum response at the output to a signal of varying frequency (but constant amplitude) at its input. In the audible range it is usually referred to in connection with electronic amplifiers, microphones and… …
3Frequency capping — is a term in advertising that means restricting (capping) the amount of times (frequency) a specific visitor to a website is shown a particular advertisement. This restriction is applied to all websites that serve ads from the same advertising… …
4Frequency Scanning Interferometry — (FSI) is an absolute distance measurement technique, for measuring the distance between a pair of points, along a line of sight. The power of the FSI technique lies in its ability to make many such distance measurements, simultaneously. For each… …
5Frequency — For other uses, see Frequency (disambiguation). Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s) …
6Frequency-resolved optical gating — In optics, frequency resolved optical gating (FROG) is a derivative of autocorrelation, but is far superior in its ability to measure ultrafast optical pulse shapes. Further, it can determine the phase of the pulse.In the most common… …
7frequency meter — ▪ measurement device device for measuring the repetitions per unit of time (customarily, a second) of a complete electromagnetic waveform. Various types of frequency meters are used. Many are instruments of the deflection type, ordinarily… …
8Frequency comb — A frequency comb is the graphic representation of the spectrum of a mode locked laser. An octave spanning comb can be used for mapping radio frequencies into the optical frequency range or it can be used to steer a piezoelectric mirror within a… …
9Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… …
10measured adj — According to this sonograph, the average frequency of my voice is 160 Hz, said Tom in measured tones …
