Abstract
A multiple reproducing repeater station system having a plurality of repeater stations connected in tandem. Each of the repeater stations comprises a logical circuit for decoding data from a pulse-modulated signal transmitted from the preceding repeater station and delivering decoded data to a processing circuit, and a PLL for extracting a clock signal from the pulse-modulated signal. The PLL has an operational response time which is so adjusted as to be different from a data delay time due to a logical operation within the logical circuit.
