PROBLEM TO BE SOLVED: To improve the locking characteristic by using a discrimination feedback type equalizer so as to allow the equalizer to be reset for a time sufficiently till automatic gain control restores to a normal state. SOLUTION: An intermittent reset generating circuit 16 generates an intermittent reset signal S9A with a long reset period based on a reset signal S8A and uses the intermittent reset signal to control a discrimination feedback type equalizer 12. The intermittent reset generating circuit 16 is made up of an N-adic binary counter and a frequency divider that frequency-divides its rip carrier output. |
