PURPOSE:To evade the production of time delay and to eliminate the effect of noise by providing a band pass filter tuned to a fundamental frequency of a clock signal to a clock signal path at the reception side of a device transmitting/receiving the clock signal. CONSTITUTION:A receiver B uses a band pass filter comprising a coil L and a capacitor C1 to select only a fundamental frequency of a clock signal. In such a case, the band pass filter is turned to the fundamental frequency of the clock signal to evade the production of the time delay. The signal through the band pass filter receives a bias by a resistor R, diodes D1, D2 and a capacitor C2 and the result is supplied to a buffer 3 of the receiver B. Thus, the signal except the clock signal such as noise having a high frequency component is eliminated and the occurrence of the time delay of the clock signal is evaded. |
