What is a regenerative repeater?

  • A.One powered by solar panels at a remote unattended site
  • B.One that reflects the signal passively towards the next station
  • C.One that demodulates and retransmits a clean copy of the signal
  • D.One that amplifies the signal without demodulating it at all

Answer: C

A regenerative repeater recovers the data, removes accumulated noise and distortion and transmits a fresh signal, so impairments do not build up along a long chain. A non-regenerative repeater amplifies noise along with the signal, and the degradation accumulates hop by hop. Power supply arrangements and passive reflection are different matters. Restoring a signal to its ideal form at each stage is what allows a digital chain to be arbitrarily long, and it is the central advantage of digital transmission.
