    • A clock signal reproducing network for PCM signal reception is capable of reproducing a clock signal even if the clock component is absent in the input digital signal for a prolonged period of time. The network includes a clock signal component extracting circuit and a bandpass filter for extracting and band-limiting the clock signal component in a received digital signal. An envelope detection circuit and a level decision circuit are connected to receive the output of the bandpass filter to provide a control signal to an output switching circuit. When the amplitude of the envelope of the filter output is high, the output of the bandpass filter is used directly as a reproduced clock signal. When the amplitude of the envelope is low, the clock signal obtained immediately before the filter amplitude becomes small is derived repeatedly from a delay circuit as a substituted clock signal.
    • 即使长时间在输入数字信号中不存在时钟分量,用于PCM信号接收的时钟信号再现网络能够再现时钟信号。 网络包括时钟信号分量提取电路和带通滤波器,用于提取和限制接收的数字信号中的时钟信号分量。 连接包络检测电路和电平判定电路以接收带通滤波器的输出以向输出开关电路提供控制信号。 当滤波器输出的包络的幅度高时,带通滤波器的输出被直接用作再现的时钟信号。 当包络的振幅低时,紧接在滤波器幅度变小之前获得的时钟信号作为替代时钟信号从延迟电路重复地导出。
