かるため素子の実装方法によって（は反射が問題となる
。Conventional configurations and their problems In general, when the signal delay due to wiring becomes comparable to the switching operation time of the element used, signal reflection becomes a problem. In recent years, some of the 1llin or earlier circuit elements with the lowest gate stage or flip-flop, which are commonly used, operate at several n5ecs, and even if the Iha propagates at the speed of light, it will propagate only 30 cm. Since it takes 1 nSe'c to do this, reflection becomes a problem depending on how the element is mounted.

問題点かあった。Conventionally, to deal with such reflections, a method has been adopted in which a terminating resistor 4 is inserted at the receiving end to match the impedance between the transmission line and the receiving end, as shown in FIG. However, as the number of signal lines increases, the number of parts also increases, leading to problems such as a decrease in packaging density or a complicated pattern on the printed circuit board.
