These special receiver stations then take in the narrow-band signal and report their data via Wi-Fi.

This narrow-band signal has a much greater range than Wi-Fi, so the number of receivers required for the project are far fewer than the number of Wi-Fi access points covering the same area.

The two worked silently, leaving behind their equipment and a narrow-band homing signal so that others could find it, should it ever need repair.

Previous searches by SETI@home have looked for extraterrestrial communications in the form of narrow-band signals, analogous to our own radio stations.

Regenerative Detectors work well for narrow-band signals, especially for CW and SSB which need a heterodyne oscillator or BFO.

The authors noted that the EMD is limited in distinguishing different components in narrow-band signals.

The processors here on the Ølvira were taking the narrow-band signal from Fleet Central, fleshing it out with detailed (and out of date) background and evoking the image shown.

We'll divert just enough power to the array to receive a narrow-band signal from the probe.

Any strong narrow-band signal that remains in a single channel we take very seriously.

In SSW, a narrow-band signal is transmitted over a much larger bandwidth such that the signal energy presented in any signal frequency is undetectable.
