The phrase "amplitude of the second" is correct and usable in written English.
It can be used in contexts related to physics, engineering, or music, where you are discussing the amplitude of a wave or signal measured in seconds.
Example: "In the analysis of the sound wave, we measured the amplitude of the second peak to determine its intensity."
Alternatives: "magnitude of the second" or "height of the second".
For analysis, we calculated the maximal response strength (amplitude) in terms of spikes per bin to each of both stimuli in the PSTHs using a bin width of 1 ms. The ratio (A2/A1) between the amplitude of the second (A2) and first (A1) response was taken as measure of the PPS of SI neurons.
Our analysis focused on the amplitude of the second negative component, which was sensitive to BM.
Chaotic behavior is found in terms of the amplitude of the second external force.
The amplitude of the second derivative peak of MLT was measured at 324.0 nm.
Therefore, the amplitude of the second harmonic wave mode is oscillating with increasing propagation distance.
The amplitude of the second SC was 310 nT at Alibag and larger than 273 nT at Kakioka as mentioned above.
The nonlinear simulation using the GCMT slip model also precisely reproduced the arrival time and amplitude of the second positive wave recorded inside Sendai Bay (amplitude = 1.65 m).
By solving the UCA's dynamical equation analytically, the effect that the chirp signal parameters and the UCA shell parameters have on the amplitude of the second harmonic frequency are examined.
In the P50 suppression paradigm, when two auditory stimuli are presented 500 ms apart, the amplitude of the second response (S2), compared with the first (S1), is markedly attenuated in healthy subjects.
The amplitude of the second-derivative-emission spectrum, corresponding to the evaporated and re-dissolved organic phase, between 353 and 361 nm has been employed as analytical signal.
Employing the photoinduced emission signal at 361 nm or the amplitude of the second-derivative-photoinduced emission spectrum, between 353 and 361 nm, a linear relation is found in the assayed range 5.7 31.4 ng mL−1 of trans-piceid and limits of detection of 1.7 and 2.1 ng mL−1, respectively, are obtained.
