ABSTRACT:
Disclosed is a duplex system having a function to suppress radio wave radiation. To suppress unnecessary radiation of radio waves from duplex clock signal lines, the system comprises a plurality of cards each for mounting electronic devices, a backboard for supporting the plurality of cards to be standing closely together in parallel, a first and a second clock signal sources for respectively generating a first and a second clock signals, a first and a second selecting gates for alternatively selecting one of the first and second clock signals to be output, and a first and a second group of clock signal lines, the clock signal lines in the first and second group respectively being wired closely in parallel on the backboard and wired on the cards, for respectively conducting the first and second clock signals to the cards.
