Given the possibilities," he adds, "why are most things done within such a narrow bandwidth?

The concept uses frequency shifting to overcome the narrow bandwidth of regular telephone systems.

These structures can achieve a negative index of refraction only within a narrow bandwidth.

For a few hundred feet we're surrounded by saguaros, but soon we've passed their narrow bandwidth and there's none to be seen.

Across the spectrum, narrow bandwidths spiked as if they were screaming.

Using technology that can support narrower bandwidths in general allows more efficient use of the licensed block.

Many of these noise sources are narrow bandwidth and therefore can be avoided.

This narrow bandwidth of radiation falls on an infrared detector.

If the system under test were to radiate all its energy in a narrow bandwidth, it would register a large peak.

The instruments have a narrow 2nm optical bandwidth over the wavelength range 190nm-1000nm.
