The phrase "an appropriate frequency" is correct and usable in written English.
It can be used when discussing the suitability or adequacy of a specific frequency in various contexts, such as communication, data transmission, or scheduling.
Example: "To ensure effective communication, we need to establish an appropriate frequency for our meetings."
Alternatives: "a suitable frequency" or "an adequate frequency".
"It does a really good job of bluffing with an appropriate frequency, as well as check raising and slow playing".
To do all this, though, you need a device called a transducer.Transducers are made from arrays of tiny piezoelectric structures that convert electrical signals into ultrasound waves by vibrating at an appropriate frequency.
What is needed are smaller rectifiers which would, by very dint of their size, rectify current of an appropriate frequency.If that could be done, a new type of solar cell would be available.
Further studies will be necessary to develop protocols to determine an appropriate frequency of sludge removal from WWT-MFCs depending on wastewater qualities.
Moreover, a yawing force at an appropriate frequency is able to correct the gun azimuth and elevation perturbation to some extent.
In particular it describes the behaviour of a suspended gas bubble irradiated with sound of an appropriate frequency and pressure to induce bubble wall oscillation.
Simulation and experimental results show that proposed scheme can achieve an appropriate frequency-load control among parallel synchronous generators, and ensure their stable and economical performances.
In future work, the proposed framework can be extended to add a selection of appropriate frequency band and type of the CR spectrum access for multi-band CR operation in heterogeneous environment and to investigate implementation of the fuzzy logic membership function for the interference categorization.
The transport rate was increased by applying a high voltage of appropriate frequency.
In the car, you select the appropriate frequency from a playlist the way you would a song.
The Anaconda wave energy device consists of a pressurised flooded tube, which when excited with an external incident wave of appropriate frequency, for the set inflation pressure, permits generation of internal bulge waves that provide the mechanism for more efficient wave energy extraction.
