Title: Light reception circuit for burst data
Inventor: NAITO SEIGO
IPC: H04B10/2507
Filed: 1987-04-03
Abstract: PURPOSE:To prevent the condition that an error pulse is outputted by a noise at the time of a silence and the condition is held by detecting the condition that a signal input is eliminated and setting the threshold voltage of a comparator to an initial value then. CONSTITUTION:When a signal detecting circuit 11 detects the absence of a light signal, an initial value setting circuit 12 switches the threshold of a comparator 4 for a constant time and sets the signal output of the comparator to either of '1' or '0' specified beforehand. When the signal detecting circuit detects the absence of the light signal, a noise pulse occurs, thus, an erroneous action is executed, the signal output of the comparator is inverted to the condition opposite to the condition specified beforehand, and then, the threshold of the comparator is switched in accordance with the inverting output and the signal detecting circuit also detects the presence of the light signal temporarily. Thereafter, the signal detecting circuit outputs the detecting signal of a signal, this is operated to the initial value setting circuit and the threshold switched in accordance with the inverting output is switched again and returned to an original initial level. After the threshold returned to the original level and the differential output at the time of the silence are compared, the comparator changes the output inverted by the erroneous action and sets it to an '1' or '0' condition specified beforehand.
