Chen et al. [4] proposed the dynamic frequency selection approach, in which each connection selects its subchannel according to the probability distribution, where the selection probability is determined by channel quality.
Nowadays, excitation sculpting is probably the most efficient way to achieve selectivity in an NMR experiment, since it associates very clean frequency selection with "user-friendliness".
With careful frequency selection the formaldehyde signals were not observed.
The frequency selection will scale the ADC read period to twice the selection, the Nyquist rate for the particular input.
In this paper, a new frequency selection method for efficient FRF-based model updating is proposed.
Frequency selection depends on the material properties and structure in the biomass mixture.
If noncoherent sampling is chosen, the input frequency selection has fewer restrictions.
This acoustic frequency selection assists the insect in predation and swarming.
Furthermore, the unwrapping accuracy can nearly reach 100% if the frequency selection rule is satisfied.
The military-industry debate also involves the merits of a technical standard known as dynamic frequency selection, which is being used by advanced wireless Internet radios overseas to avoid interference.
Military officials are asking the American industry, and companies in other countries, to create and install even more sensitive versions of dynamic frequency selection -- something that the companies say may cause the technology to operate incorrectly.
