PURPOSE:To prevent data error even if a pulse is received from a non-signal state by providing a delay circuit to a main channel to compensate the delay of a sub-channel due to a timing circuit. CONSTITUTION:An output signal of an equalizing amplifier circuit 1 is as shown in (a) and becomes an input to the timing circuit 2 and an input to the delay circuit 4. Moreover, an output signal of the timing circuit 2 becomes a signal shown in (c), and a delay time difference due to the passing through the timing circuit 2 is produced between the waveforms of the signals (a) and (c). An output signal (b) of the delay circuit 4 when the waveform of the signal (a) is inputted becomes an input data signal of a regenerating circuit 3, and the delay circuit 2 has a delay time at least equal to or over the delay time of the timing circuit 2. Thus, the production of identification error of the regnerating circuit caused by the delay time of the timing circuit 2 is prevented. |
