ABSTRACT:
A frequency modulated signal reproducing device comprises a reproducing device for reproducing a frequency modulated signal from a recording medium; a pilot signal generating device for generating a pilot signal relative to a discontinued part of the signal reproduced by the reproducing means; a phase lock device which generates a phase locked signal which is phase locked relative to the reproduced signal; a demodulating device for frequency demodulating the phase locked signal; and control means for controlling the response speed of the phase lock means on the basis of the pilot signal.
