The phrase "amplitude and number of" is correct and usable in written English.
It can be used when discussing measurements or characteristics of a phenomenon, particularly in scientific or technical contexts.
Example: "The amplitude and number of oscillations in the wave were recorded for analysis."
Alternatives: "magnitude and quantity of" or "size and count of".
Movement parameters (velocity, frequency, amplitude, and number of arrests) were assessed during a finger tapping task.
Moreover, we quantify the non-linear artifacts as a function of both multisine amplitude and number of frequencies.
Results indicated promoted proliferation of hMSCs by cyclic strain, enhanced by elevated strain amplitude and number of cycles.
The unloading stiffness of the bucket foundations decreased with the increase in load amplitude and number of cycles.
As the concentration of oxytocin increased, the energy, amplitude, and number of bursts per unit time declined while the intrauterine pressure continued to rise until the contraction became tetanic, without return to the baseline.
An analytical model, which considers the effects of the initial residual stress, yield stress, stress amplitude, and number of cycles, was proposed to predict the relaxation of the weld residual stress by the cyclic load.
By means of this scheme, we explore numerically the relationship between the boundary data and the amplitudes and number of solitary waves it produces.
The amplitude, frequency and number of oscillating movements have a significant impact on the possible damage modes of rolling bearings.
It is observed that the amplitude, orientation and number of lobes can change significantly for some small frequency intervals, of the order of 100 Hz; these are shown to be caused by higher order modes.
We have defined three new features of the electromyographic (EMG) interference pattern (IP): activity, upper centile amplitude (UCA), and number of small segments (NSS).
We investigated nerve recruitment, cardiovascular responses, and skeletal muscle responses to different temporal patterns of VNS across 39 combinations of stimulation amplitude, frequency, and number of pulses per burst.
