PURPOSE:To obtain a small-sized automatic equalizer suitable for the formation of LSI by constituting an identified result feedback route for the equalizer of plural circuit networks consisting of a primary circuit network consists of an electrostatic capacitor and a resistor and a multiplier changing the weight of the primary circuit network. CONSTITUTION:A transmission data signal is passed through a transmission line 8 and added to a signal from a feedback route 9 by an adder 5 and the added signal is inputted to a data identification circuit 10. The circuit 10 compares the amplitude of the signal at the time of identification with a previously fixed threshold to estimate and to restore the data signal. The feedback line 9 is constituted of plural circuit networks consisting of the primary circuit networks 2 each of which consists of a resistor Ri and an electrostatic capacitor C and multipliers 3 changing the voltage weight by weight di. The output of the circuit network is added to the signal inputted through the transmission line 8 by the adder 5 and the added result is identified by the circuit 10, and automatically equalized in accordance with the state of the transmission line 8, then outputted. |
