Filed: 1987-06-29
Abstract: PURPOSE:To expand the dynamic range of an optical signal reception level by providing a monostable multivibrator between a comparator and an integration device of an optical reception circuit. CONSTITUTION:The monostable multivibrator 4 inserted between a comparator 3 and an integration device 5 to equalize the detection output signal 13 of the comparator 3 is provided. An optical signal 11 modulated from the original data signal 10 by a carrier component is converted into a signal 12 by a photodetector 1 and an AC amplifier 2.
