##### Displacement Amplitude

The quantity X is the single-peak amplitude, and x travels between the limits ±X, so the peak-to-peak amplitude (also known as double amplitude) is 2X. It appears to be an accepted convention to express displacements as double amplitudes, but velocities and accelerations as single-peak amplitudes, so some care is needed, especially when interpreting vibration test specifications.
