PURPOSE:To allow the circuit to cope with a signal transmission system even in a digital signal transmission system by any form of a band pass filter timing circuit section or a PLL timing circuit section. CONSTITUTION:The digital transmission system timing circuit equipped to a reception terminal station is provided with a band pass filter timing circuit section 4 and a PLL timing circuit section 5 and any of the band pass filter timing circuit section 4 or the PLL timing circuit section 5 is selected by a changeover circuit section 6 based on the quantity of jitter in a sent data string. |
