摘要：PURPOSE:To realize highly accurate automatic equalization by arranging a circuit network comprising a ladder circuit network consisting of a capacitor and a resistor and a changeover circuit to the pre-stage of an amplifier and changing over the switch according to the characteristic of a transmission line. CONSTITUTION:An input signal from a terminal 1 is divided to paths comprising a resistor R2 and a capacitor group, and the signals are added by an adder 5. The signal to the capacitor group is changed over by a switch group 7 and the level is changed depending on the selected switch position of the switch group 7. A signal having no interference between codes is obtained automatically by changing the switch position in response to the change in the transmission line such as line length and changing a transfer function to the voltage.
