The phrase "and frequency can be" is correct and usable in written English.
It can be used in contexts discussing the potential or capability of frequency in various situations, such as scientific or technical discussions.
Example: "The data shows that the signal strength varies, and frequency can be adjusted to optimize performance."
Alternatives: "and frequency may be" or "and frequency is able to be".
We demonstrate that both the vibration amplitude and frequency can be quantified, in the frequency range 0 250 Hz, with an axial resolution of 1 μm.
The velocity, displacement, and frequency can be acquired by demodulating the phase-modulated Doppler signal and processing the data by software.
Employing one matrix inversion, a large number of terms of the perturbation series of the displacement and frequency can be easily computed with a small computation time.
The effect of a uniform external electric field in the chemisorbed CO geometry and frequency can be understood by using the concept of 'surface wall'.
But whether The Wire is a successful example of this serialised, episodic form is open for debate; the programme seems to be much more successful as one of a new breed of made-for-box-set programmes whose duration and frequency can be controlled by the viewer than as a last glorious flowering of the now-venerable serial form.
In the transition region between apparent charge transfer and full mass transport control characteristic oscillations are observed, whose amplitude and frequency can be controlled by potential and magnetic field strength.
Their characteristic wavelengths and frequencies can be demonstrated and measured through the interference effects that result from the overlap of two or more waves in space.
Voltage and frequencies can be best adjusted if we know the workload in advance, or its constant throughout the execution.
Non-stationary signals which are a compound of constituents with time-varying amplitudes and frequencies can be characterized by amplitude-modulated frequency-modulated (AM-FM) models.
The optimum flux-weakening current and PWM frequency can be quickly found, and optimal effects of energy loss are verified by theoretical analysis and experimental results.
