Abstract
A phase slip detector and systems employing said detector comprises a frequency detector for detecting an instantaneous value of received carrier frequency and an integrator for integrating the output of said detector, and determines an occurrence of phase slip by detecting the output level of the integrator larger than predetermind threshold level. Application of the phase slip detector to a carrier recovery system makes it possible to obtain a correct recovered carrier without the effect of phase slip, and application of the detector to a demodulated data compensation system makes it possible to obtain received or demodulated data compressed in generation of burst error and free from the effect of the phase slip.
