amplitude

Both the frequency and the amplitude of the changes are increasing.

The performance loss is partly due to the difficulty of optimizing the shape and amplitude of the applied magnetic perturbations, which in turn stems from the computational intensity of existing physics-based optimization approaches.

It has been well documented that a song's volume, or loudness, over time -- what's known as "amplitude modulation" -- is relatively steady at 1-2 Hz.

Contrasting the observed unusual electrical activity, the spontaneous isomerization of G90D rhodopsin demonstrated a high amplitude but low frequency.

"Depending on our actions, we can reduce the speed of that warming, and we can decrease the overall amplitude of that warming and sea-level rise."
