In this "pushed wave" regime, the spatial spreading of gene drives will be initiated only when the initial frequency distribution is above a threshold profile called "critical propagule," which acts as a safeguard against accidental release.
However, it is sensitive to the initial frequency value.
A signal received by the antenna is sent back as a harmonic, or multiple of the initial frequency, enabling researchers to sort out the tiny bee from background echoes.
Through frequency sensitivity analysis, the acoustic performance can be obtained near the initial frequency for less cost than a second full analysis.
Table 4 lists the initial frequency of the structure before the test.
The initial frequency and chirp rate parameter values are as follows:,,,,,,,.
We assign SNR = 5 dB and the initial frequency grid point as g(0) = 9/M.
However, most research only considers a modal analysis of the initial frequency.
The initial frequency and amplitude can be obtained by the dechirp technique and fast Fourier transform.
where f dc and k d denote the initial frequency and the chirp rate, respectively.
For example, if the initial frequency is 32 Hz, the number of steps is 5.
