The phrase "a zero frequency" is correct and usable in written English.
It can be used in contexts related to physics, signal processing, or any field discussing frequencies, indicating the absence of a signal or oscillation.
Example: "In this experiment, we observed a zero frequency response, indicating that there was no detectable signal."
Alternatives: "no frequency" or "null frequency".
When I send in a zero frequency, constant, I get what output?
At a zero frequency value, this function represents a ratio of time-averaged intensity at the receiving point to time-averaged power input at the source point, and at all other frequencies the frequency response function represents a ratio of the amplitude of the fluctuating intensity at the receiving point to the amplitude of the fluctuating power at a source point.
Note that due to rotational symmetry, there always is a zero frequency planar mode corresponding to the free rotation of the crystal.
In all analyzed examples evaluated by the computer simulation, we essentially had a zero frequency gap between the positive and negative frequencies (spectral parts), made by omitting only one subchannel.
Since the effective potential energy is just a function of, it is rotationally symmetric around the -axis and we would expect there to be a zero frequency rotational mode in the phonon eigenvectors.
In addition, the minor allele (rs3135941C) in TEX1 showed a weak association with the subphenotype of neurologic disorder (with a zero frequency in this subphenotype, P = 0.042).
The frequency spectrum of this signal is characterized by a finite zero frequency component (DC) with an amplitude equal to mean expiratory flow.
The problem is due to the fact that all cycle by cycle mean stress effects are aggregated during the Fourier transform process into a single zero frequency content.
aOne item (シェアー /sheaa/ share) was not found in the Amano and Kondo (2000) corpus; hence, a single zero frequency is included in the data set.
In the context of CA in an LTE-A scenario, two frequency bands, i.e. two CCs, are available to the operator.
Typically, although not always, the period doubling curves extended to a cusp at zero frequency in the amplitude vs frequency bifurcation diagram.
