Title: Optical receiver
Inventor: SAITO KATSUMI
IPC: H04B10/556
Filed: 1988-04-11
Abstract: PURPOSE:To well receive a binary optical signal which is discontinuous and large in the change of an optical reception electric power with a simple constitution by amplifying and signal-discriminating after differentiating the binary intensity modulated optical reception signal in a differentiating circuit and converting it into a balanced signal. CONSTITUTION:The binary intensity modulated received signal is amplified to a prescribed voltage with an amplifier 10 by being differentiated with a differentiating circuit 9 after a signal amplification is balanced to both polarities. It is detected by a first comparator 12 and a second comparator 14 that the signal turns to an upper limit setting voltage or more and to a lower limit setting voltage or below and reproduced to an original binary signal by the output of a flip flop to be set with the upper limit and lower limit detection signal and reset. Thus, since the reception signal converted into the balance signal of which signal amplitude is symmetrical to both positive and negative sides by the differentiating, the influence of a transit response by the alternating current combination of a capacitor, since an idling pulse and a guard time are made unnecessary, a transmission efficiency is improved.
