The phrase "avoid frequencies" is correct and usable in written English.
It can be used in contexts related to sound, communication, or any situation where certain frequencies are undesirable or should be minimized.
Example: "To improve the quality of the audio, we need to avoid frequencies that cause distortion."
Alternatives: "steer clear of frequencies" or "eliminate frequencies".
The Campbell diagram approach is too conservative since bladed wheels show many close frequency natural modes, thus it is almost impossible to avoid frequency matching.
Power gradient limit determines the constraints of ramp rate to avoid frequency deviation, especially when active power provided by WPPs varies rapidly [21].
Radio networks for future mobile communications systems, for example, 3GPP Long-Term Evolution (LTE), are likely to use an orthogonal frequency division multiplexing- (OFDM-) based air interface in the downlink with a frequency reuse factor of one to avoid frequency planning.
However, a more efficient method to maximize the use of the available spectrum would be to not simply avoid frequency bands that are in use, but rather to limit the amount of in-band transmission down to an acceptable low level so as to avoid interfering with the original user.
For molecular analyses, 1 2 isolates from each vial were analyzed to avoid frequency biases attributable to potential germline jackpot events (Luria and Delbruck. 1943).
And it wouldn't be a problem if the white-space gadgets work as intended, avoiding frequencies where there is any conflict.
The results show a marked improvement in frequency nadirs, while avoiding frequency overshoots and avoiding contracted load shedding.
Based on differing dynamic response and load availability patterns of flexible end uses, it aims to enhance the frequency response while avoiding frequency overshoots, and minimising communication requirements.
A major feature of Long Term Evolution (LTE) Uplink (UL) is the Single Carrier Frequency Division Multiple Access (SC-FDMA) transmission scheme which separates signals from different user equipments (UEs) by frequency and, therefore, avoids frequency overlap between different signals.
It is possible to avoid authorized frequencies based on frequency hopping technique [34]; but in this mechanism, UWB sensors can only use one single free band, resulting in rather low spectrum utilization.
