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