ABSTRACT:
A digital signal transmission circuit for transmitting an input pulse signal to receiving circuits through transmission lines. The digital signal transmission circuit is provided with a phase converting circuit for outputting a first output signal and a second output signal delayed in phase with respect to the first output signal according to the input of the pulse signal, a first transmission line included in the transmission lines, for transmitting the first output signal, a second transmission line included in the transmission lines, for transmitting the second output signal, and a pair of phase decoding circuits for receiving the first and second output signals from the first and second transmission lines and outputting pulse signals according to the state of reception of the first and second output signals. Thus, pulse signals to be transmitted can be restored based on a difference in delay between the first and second output signals received by the phase decoding circuits so that high-accuracy digital signal transmission is performed.
