Abstract
A signal transmission circuit in which a signal is converted into two complementary signals which are outputted from a signal transmission circuit via series resistors. The amplitude of each of the complimentary signals is reduced by the series resistors and terminating resistors provided on a signal receiving side. The signal receiving side shifts the level of the signals which it inputs. The level shifted signals are amplified by a high-input impedance differential amplifying circuit.
