The phrase "alternative frequencies" is correct and usable in written English.
It can be used in contexts related to communication, technology, or radio signals where different frequencies are being discussed or utilized.
Example: "The device can operate on alternative frequencies to improve signal clarity and reduce interference."
Alternatives: "different frequencies" or "varied frequencies".
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).
For example, one prediction from the AN1-tuning is that all frequencies which exhibit lower thresholds compared to alternative frequencies should be preferred.
The Red index reflects the unbalance of response alternative frequencies in a sequence that derives from a more frequent usage of given numbers than expected based on the theoretical frequency of each digit in random responses.
The alternative frequencies for food and drink items were 'rarely/never', '1 3 times a month', '1 3 times a week', '4 6 times a week'oncence a day'twiceice a day' and '3 or more times per day'.
In the present experiment, a perfect equality of response alternative frequencies corresponds to the generation of each number from 1 to 10 seven times each and would lead to a Red score of 0% (no redundancy), whereas repeating the same digit along the whole sequence would lead to a Red score of 100% (complete redundancy).
Here, an alternative, frequency-related, hierarchy is frequently applied7.
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.
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.
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.
