A first average detecting circuit detects an average of output signals of a pre-amplifying unit that controls an amplification gain based on a result of comparison between an output of the first average detecting circuit and a predetermined reference voltage. A discriminating circuit receives an output signal of the pre-amplifying unit as an input signal and performs a signal discrimination of the input signal based on a threshold. A second average detecting circuit detects an average of input signals to the discriminating circuit. The discriminating circuit receives an output of the second average detecting circuit as the threshold.
An optical receiver comprising:
A discrimination-threshold generating method for an optical receiver, the optical receiver including a pre-amplifying unit that performs voltage conversion and amplification of an output of a light-receiving element that receives a light signal and converts the received light signal into a current signal, and a regenerating unit including a discriminating circuit that receives an output signal of the pre-amplifying unit as an input signal and performs a signal discrimination of the input signal based on a threshold generated based on the input signal, the discrimination-threshold generating method comprising:
