摘要：
A light receiving circuit includes: a filter, arranged in a downstream of an electric signal amplifier to amplify an electric signal based on a light signal, to adjust a bandwidth of an amplified electric signal; a monitor circuit to monitor a communication quality of the light signal and output a monitored value; and a control circuit to control a bandwidth of the filter based on a control value corresponding to the monitored value.
