Abstract:
There is provided a signal transfer system that has a driver for outputting a signal, a transmission line for transmitting the signal, an insertion-type attenuator, inserted into the transmission line in series, for largely attenuating the low-frequency signal more than a high-frequency signal and an additional-type attenuator, inserted between the transmission line and a reference potential, for largely attenuating the low-frequency signal more than the high-frequency signal, and that matches composite impedance generated by the driver, the insertion-type attenuator and the additional-type attenuator with impedance of the transmission line.
