sine wave

The filament appears to wobble up and down like a sine wave over the course of thousands of light-years.

One reason this model makes for an excellent UPS for your home network is that it gives output power in a pure sine wave form.

A sine-wave inverter allows a UPS to produce a clean sine wave form, which is the best type for power output.

Any set of data plotted over time can be expressed as a sum of trigonometric functions like sine waves, which can be expressed in terms of their frequency and amplitude.

Once the communicator's standby light approached sine-wave modulation.
