PROBLEM TO BE SOLVED: To early take bit synchronism to a degraded input signal. SOLUTION: When the repetition of bits in the input signal is detected by an S/P converter 6 for sampling the input signal with the rising edge of a reproducing clock provided by a digital control oscillator 3 without detecting the bit repetition of the input signal through an S/P converter 5 for sampling the input signal with the falling edge of the same reproducing clock, the reproducing clock is inverted by controlling the digital control oscillator 3 so that a normal bit synchronizing signal can be provided from the S/ P converter 5. |
