The phrase "is a frequency" is a correct and usable phrase in written English, and can be used in a variety of contexts.
For example, "Electromagnetic radiation is a frequency measured in hertz."
The most commonly used tabular summary of data for a single variable is a frequency distribution.
The $399 Dual zBoost Extender is a frequency booster for 800/1900MHz cell signals.
However, FFR is a frequency domain interference management technique.
The second approach is a frequency domain filtering, a.k.a.a
In fact, there is a frequency reduction, which can be explained by classical structural dynamics.
This method is commonly called the Werzungzahl (Wz) method which is a frequency weighted r.m.s.
When the frequency assignment and subsequent combining is done at a central point, the resulting combination is a frequency-division multiplexed signal, as is discussed in Multiplexing.
where is a frequency-smoothing window.
Otherwise we say there is a frequency-selective fading.
Originally, CR is a frequency-agile radio, capable of accessing licensed spectrum without influencing the primary users[3].
After Fourier transformation, the result of a NMR experiment (of arbitrary dimensionality) is a frequency-domain spectrum.
