PURPOSE: To provide a bus terminating method for transmitting a high frequency digital signal capable of transmitting a digital signal with a cyclic frequency in a GHz band while using a conventional terminal resistor. CONSTITUTION: A terminal resistor is connected to the edge part of a bus arranged on a wiring board, and an insulator whose dielectric loss angle δ (dielectric tan δ) is large is arranged in the surrounding or in the vicinity of the terminal resistance so that high frequency components can be absorbed. 배선 기판 상에 형성된 버스의 일 단부에 종단 저항기가 설치된다. 이 종단 저항기 주변에 큰 유전체 손실각을 가지는 절연물을 설치하여 그 주변의 고주파 전자파를 흡수한다. 이러한 구성은, 종래의 종단 저항기를 사용하여 ㎓ 대의 디지털 신호를 성공적으로 전송하게 한다.
