Record 1 2011-03-31

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Telecommunications Transmission
DEF

A device used to extend the length, topology, or interconnectivity of a single-channel phase-coherent-FSK [frequency-shift keying] bus local area network beyond the limits imposed by the minimum transmit and receive level specifications of the station.

OBS

Regenerative repeaters perform the basic actions of restoring signal amplitude, waveform, and timing. They also prefix enough preamble signaling to a transmission to compensate for any loss in transmission from the prior station or repeater.

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Transmission (Télécommunications)
DEF

Dispositif dont l'usage permet de reconstituer un signal altéré, selon des valeurs de références, en un signal équivalent aux spécifications d'origine.

English

Subject field(s)
  • Telecommunications
