The phrase "a frequency that could" is correct and usable in written English.
It can be used when discussing potential or hypothetical frequencies in various contexts, such as science, technology, or communication.
Example: "The researchers identified a frequency that could enhance the signal strength in the transmission."
Alternatives: "a frequency capable of" or "a frequency that might".
The components were relays -- devices about the size of a microwave oven, installed at critical nodes along the power grid, that are supposed to protect its key components by disconnecting them in the event of a change in current, voltage or frequency that could cause damage.
Our high spatial frequency, however, was only 3.6 cycles/°-, because the projection system in the scanner environment placed an upper limit on the spatial frequency that could be used.
In 2004, standards became looser, because industry modelers decided to use a new approach -- basically doubling the amount of radio frequency that could reach the brain of an adult and quadrupling that reaching a child's.
The major interventions that targeted high volume laboratory tests were introduction of electronic duplicate test cancellation and modification of the allowable options for repetitive frequency that could be selected in a single electronic order (Table 4, Additional file 1).
The group concluded that any effect on biological systems would require a nonlinear biological interaction that operated on the time scale of the carrier frequency that could demodulate the amplitude-modulated component (Challis 2005; NRPB 2001; Valberg et al. 2007).
Hackers will recognize 2600hz as the frequency that could be hacked to access the telco networks and make free calls.
Among the remaining text lines, there were still some polarity shifting patterns of low frequency that could be fully annotated manually if so desired.
This might lead to filtering out some fundamental frequency that could result in pitch reversals of tones or degradations in the perceived sound quality.
However, the stimulation frequency of 100 Hz used in that study was greater than the maximum frequency that could be achieved by the percussor used in the present study.
Further, we could estimate the increase in consultation frequency that could be considered to be attributable to the neck injury, for example, taking into account the regression to the mean phenomenon.
