The phrase "alternative frequency" is correct and usable in written English.
It can be used in contexts related to communication, broadcasting, or technology where different frequencies are being discussed or utilized.
Example: "In case of interference on the main channel, please switch to the alternative frequency for clearer reception."
Alternatives: "substitute frequency" or "different frequency".
An alternative frequency domain procedure is applicable under the hypothesis of stationary Gaussian stress state.
We propose an alternative frequency assignment scheme to reduce FWM crosstalk by allocating frequencies to a set of unevenly spaced channels determined by an optical spreading code.
Our analysis indicated that the VPAD-based weighting was fairly consistent with the finger surface vibration transmissibility at frequencies greater than the first resonance, suggesting that the finger surface transmissibility may be used as an alternative frequency weighting for assessing the finger vibration exposure.
And to what extent does that bound depend on the prior probabilities of the various possible alternative frequency hypotheses.
Exploiting portions of the spectrum to unlicensed usage was a first step to introducing alternative frequency management schemes.
Eventually, we also performed a control analysis using alternative frequency datasets, to account for possible anomalies in the Google dataset due to its online origin.
Here, an alternative, frequency-related, hierarchy is frequently applied7.
In the framework of the random vibration of linear systems, alternative frequency- and time-domain approaches to evaluate the correlation coefficients of SDoF oscillators with viscoelastic memory are presented, and validated by means of Monte Carlo simulation.
An alternative frequency-dependent approach was explored for a single array in our previous works [15, 16], using either a time domain implementation or a frequency domain implementation.
In recent years, alternative frequencies for future warships have been considered.
In the 5G over 700MHz scenario, Ofcom notes that although alternative frequencies will need to be provided for digital terrestrial TV (likely in the 600MHz band), in most cases it says this will only require a retune of existing TV equipment, rather than the replacement of roof-top aerials (although it says a minority of consumers will need to switch aerials).
