Title: Receiving circuit for optical binary signal
Inventor: SHOJI NOBORU
IPC: H04B10/07
Filed: 1985-09-06
Abstract: PURPOSE:To reduce the change of a pulse width and a jitter and to increase the degree of operating allowance even when the mark ratio of a signal is not 0.5 by performing a limiter amplification after reducing fewer the rising/ falling time of the signal. CONSTITUTION:When the mark ratio of the signal is smaller than 0.5, the rising/ falling time of the output waveform [figure (a)] of a photoelectric conversion circuit 1 is set as some fixed value. The output signal, the rising/falling time of which is made smaller by a high speed operating circuit 2 as shown in figure (b), is AC-coupled with a limiter amplifier circuit 3. The circuit 3, amplifying an input signal and limiting an amplitude, outputs a signal (c) to a filter 4. The filter 4 eliminates a high frequency component generated by the circuit 2 and performs a band limitation to minimize a code error rate and outputs a signal (d) to an identification circuit 5. In the previous state, the DC operating point of the signal (b) is set below 50% of an amplitude level, however, since the rising/falling time of the signal is so small, the fluctuation of the pulse width in the output waveform from the circuit 3 can be made small.
