The phrase "at a minimum frequency" is correct and usable in written English.
It can be used when specifying the lowest allowable frequency for a particular process, event, or measurement.
Example: "The device must operate at a minimum frequency of 60 Hz to ensure proper functionality."
Alternatives: "at the lowest frequency" or "at a baseline frequency".
Exercise continued at a minimum frequency of three times weekly.
Animals were required to perform a sequence of presses at a minimum frequency in order to obtain a 20 mg food pellet (Bio-Serv, Flemington, NJ, United States).
We then enumerated SNPs at sites where coverage depth was at least 8 and where alternate alleles were present at a minimum frequency of 20%.
Here we counted SNPs at sites where coverage depth was at least 8×, and where alternate alleles were present at a minimum frequency of 20%.
On the following training sessions animals were reinforced if they performed a sequence of consecutive presses at a minimum frequency (covert target), defined by the inverse of three consecutive inter-press intervals (IPIs), which increased with training.
sPTB was defined as the occurrence of regular uterine contractions at a minimum frequency of two contractions per 10 minutes, along with cervical changes, leading to delivery before the 37th week of gestation was completed.
Common variations, such as single nucleotide polymorphisms (SNPs), occur with at least a minimum frequency in a population (commonly a minimum allele frequency of 1% is applied).
Constant voltage (2.5 V) was provided by a custom-build coupler, whose output was converted to an optical pulse with a minimum frequency of 100 Hz at 0 μS to avoid aliasing, digitally converted (Micro1401, CED, Cambridge, UK), and recorded (Spike2, CED).
We screened F1's laid over a 48-hr period after injection in pools of eight worms and identified edits at an estimated minimum frequency of 4% (experiment 13) and 0.9% (experiment 14).
Sanger sequencing confirmed that none of the SNPs detected at a minimum variant frequency of 10-20% was real.
This dependence is derived theoretically from the condition of resonance at the minimum frequency of the first-order symmetric Lamb mode.
