<p>PROBLEM TO BE SOLVED: To suppress resonance-frequency electromagnetic wave radiation caused by the multiple reflections between an output-side device and input-side devices, while the high rising speeds of signals which are transmitted from the output-side device to the input-side devices via a transmission line are secured in a device mounted on printed wiring board. SOLUTION: In the device mounted on the printed wiring board, a circuit is constituted, in such a way that the output-side device 11 which outputs the signals, the input-side devices 14a-14e which input the signals, and the transmission line 13 which connects the output end of the output-side device 11 to the input ends of the input-side devices 14a-14e transmits the signals, and has a larger impedance than the device 11 has are provided on a printed wiring board. In addition, a capacity 12 is positioned between the output end of the device 11 and a reference potential 2 and causes the resonance frequency caused by the multiple reflections between the output-side device 11 and input-side devices 14a-14e to be included in the blocking band of a filter constituted by combining the capacity 12 with the device 11.</p> |
