摘要： An electronic circuit apparatus having a bus, a plurality of stubs branched from the bus, and a plurality of semiconductor devices having signal input/output terminals connected to the corresponding stubs. The electronic circuit apparatus includes at least one impedance circuit arranged between the bus and at least one of the stubs, and each impedance circuit has a high-pass filter characteristic. Therefore, ringing is suppressed, attenuation in the high-frequency components of a transmission signal is prevented, the definition of the signal is maintained, and transmission frequency and speed are both improved.
