The phrase "at a defined frequency" is correct and usable in written English.
It can be used in contexts related to measurements, signals, or events that occur at specific intervals.
Example: "The device operates at a defined frequency to ensure optimal performance in data transmission."
Alternatives: "at a specified frequency" or "at a set frequency".
It has been observed that if the sea surface is illuminated by HF waves, then significant energy at a defined frequency shift can be received.
The study design involved overnight exposure to RF-EMR at a defined frequency (1.8 GHz), over a range of SAR values that both covered the emission characteristics of mobile phones and generated sufficient dose-response data to shed light on the underlying pathophysiological mechanisms.
Both −1 frameshifting and stop codon readthrough are site specific and occur at a defined frequency much higher than the background error rates of maintaining the reading frames.
(26) Previous studies have focused on the effects of dilution by simulated vaginal fluid and semen simulant on the rheological properties at a defined oscillatory frequency.
These results are in line with a study on Duckweed, which revealed that RF-fields at defined frequencies can inhibit growth (Tkalec et al 2005).
After obtaining stable synaptic responses for at least 15 min, we stimulated the MF CA3 pyramidal cell or the CA3 CA3 recurrent pathways with trains of repetitive stimuli at defined frequencies (0.5 or 2 Hz) for 15 min. The synaptic efficacy was assessed by measuring the peak amplitude of the MF-elicited fEPSP and the radiatum-elicited fEPSP slope (in the middle third of its rising phase).
The IDSMC will first convene prior to the start of recruitment and will then define frequency of subsequent meetings (at least annually).
This figure shows that Tc computed at fc vary significantly with Tc at other frequencies within a defined wide bandwidth.
For the Nth frame, the noisy and undesired background which arises from the first term, equals: It can be seen that when δ ≠ 0 this term produces a sinusoidal behavior versus the number of frames at a frequency defined both by the exposure time and by the delay between frames.
This algorithm selects a codon for each position at a probability defined in a codon frequency lookup table.
The Gwydir wetlands could be simplified to 17 discrete patches, with each patch representing a connected landscape at defined flood frequency.
