The phrase "a desirable frequency" is correct and usable in written English.
It can be used in contexts where you are discussing an optimal or preferred rate of occurrence for something, such as events, actions, or signals.
Example: "In order to achieve the best results, we need to establish a desirable frequency for our team meetings."
Alternatives: "an ideal rate" or "a preferred interval".
In 1942 the owners of KTCB had requested permission from the F.C.C. to operate 24 hours a day and change to a more desirable frequency.
For example, Zhang et al. have proposed a per-chip adaptive frequency scaling, which partitions applications among multiple multicore chips by grouping applications with similar frequency-to-performance effects, and sets a chip-wide desirable frequency level for each chip.
Then, in the second step, a discrete-time controller is designed that achieves the desirable frequency response characteristics as close as possible, again with a numerical optimization method.
The artificial wing has to be able to maintain a fully unfolded configuration while flapping at a desirable flapping frequency.
Then, based on a desirable operating frequency, positions of closed-loop poles of the engine system are selected.
Although using high-resolution images might improve spatial accuracy and precision, it might be impossible to transfer these images from the camera to the PC at a desirable sampling frequency, because limitations of transfer depend on the camera, PC, and interface unit.
To take advantage of the degrees of freedom, provided by the GL function, parameters of filters have to be tuned to significant visual features and texture patterns, so that it can extract desirable frequency information of facial texture patterns.
Presumably, having a smaller number of options would give developers more flexibility to find appropriate associates and distractors within a particular pool (or frequency range) of words, and thus reduce the possibility of having to include less frequent words because not enough words at the desirable frequency level could be found.
The results also show that the proposed optimization algorithm can successfully overcome difficulties in opening band gap at desirable frequencies, especially for the complete band gap and multiple band gaps.
