Abstract
In a cable connecting a plurality of printed-circuit boards, terminals of connectors to which conductors disposed adjacent to conductors that supply power are connected are connected to ground via respective capacitors.
Claims6
An electronic apparatus comprising:
- a first printed-circuit board including a first connector having a first terminal, a second terminal, a third terminal and a fourth terminal;
- a second printed-circuit board including a second connector having a fifth terminal, a sixth terminal, a seventh terminal and an eighth terminal;
- and
- a cable having a plurality of conductors including a first conductor, a second conductor, a third conductor, and a fourth conductor, the cable being connected to the first connector and the second connector,
- wherein the first conductor is a line configured to transmit a signal and is connected to the first terminal of the first connector and the fifth terminal of the second connector,
- wherein the third conductor is a line configured to supply power and is connected to the third terminal of the first connector and the seventh terminal of the second connector,
- wherein the second conductor is a line configured to be connected to ground and is connected to the second terminal of the first connector and the sixth terminal of the second connector,
- wherein the fourth conductor is a line configured to be connected to ground and is connected to the fourth terminal of the first connector and the eighth terminal of the second connector,
- wherein, in the cable, the second conductor and the fourth conductor are disposed adjacent to a conductor configured to supply power,
- wherein, in the first printed-circuit board, the second terminal and the fourth terminal are each connected to ground via a plurality of capacitors whose frequency responses are different, and
- wherein, in the second printed-circuit board, the sixth terminal and the eighth terminal are each connected to ground via a plurality of capacitors whose frequency responses are different.
