A pendulum swinging in a vacuum at a constant amplitude free of external disturbances theoretically keeps perfect time.

The cycle thus generated will tend to have a constant amplitude determined by the distance between the ceiling and floor.

In order to produce a constant amplitude over the full range of the oscillator, some compensation scheme must be employed.

The human auditory system is not able to localize signals with a constant amplitude and spectrum in reverberant sound fields.

The coded data sending with constant amplitude and zero auto correlation .

The constant amplitude means the sending and receiving easily without any correction.

The tide heights are expected to follow the tidal force, with a constant amplitude and phase delay for each component.

When given an initial push, it will swing back and forth at a constant amplitude.

Measuring the power input necessary to keep the oscillator vibrating at a constant amplitude.

This usually generates a sine wave of constant amplitude often called the carrier wave, because it serves to "carry" the information through space.
