Abstract
There may be provided a receiving apparatus including: a light receiving element which receives an optical signal and generates a current signal dependent on the optical signal; a conversion unit which converts the current signal into a voltage signal; a reference voltage generation unit which generates a reference voltage; a threshold voltage generation unit which generates, based on the voltage signal outputted from the conversion unit and the reference voltage outputted from the reference voltage generation unit, a threshold voltage signal having an amplitude smaller than an amplitude of the voltage signal with reference to substantially the center of amplitude range of the voltage signal and delayed by a predetermined time period from the voltage signal; and a comparison unit which compares the voltage signal outputted from the conversion unit with the threshold voltage signal outputted from the threshold voltage generation unit.
