Description

The invention relates to automation and computer technology and can be used in conversion devices, where, during a cycle of operation, a trigger changes its state only once, as well as in devices for selecting minimal (extreme) signals.

The purpose of the invention is to increase the speed in recording information.

The drawing shows a block diagram of the device. /

The device contains an optical signal input coupler 1 and nodes 21 and 22, which contain the first 3.1 and second 3c2, third A.1 and fourth 4.2 controlled optical signal taps, lines 5.1 and 5.2 of the optical signal delay, uncontrolled 6.1 and sixth 6.2 optical signal couplers and the first 7.1 and second 7o2 photodetectors, the inputs of the electrical couplers 2 are device inputs, the second outputs of the couplers 5 are device optical outputs, the photodetector outputs 7.1 and 7.2 are electrical terminals The taps of coupler 1 are optically coupled to the inputs of the third 4 "T and fourth 4.2 taps, each node has the first output of taps 4.1 and 4, and its second output is directly connected to the first and second inputs of the taps via the lines 5.1 and 5.2 respectively 6.1 and 6.2, the outputs of which through the taps 3.1 and 3.2 on the first output are connected to the input of the photodetectors 7.1 and 7.2, the outputs of which are connected to the electrical input of the coupler 3 of the other node.

The device works as follows.

When the reference optical signal I arrives through the input coupler 1 to the inputs of nodes 2.1 and 2.2, the optical signal in each of them passes through the coupler 4 to the first output, through the coupler 6, and the coupler 3 to the first output reaches the input of the photodetector 7, which forms an electrical potential.

Since the photoreceivers of nodes 2.1 and 2.2 are not identical in time to the formation of the leading edge of an electric signal, the moments of the arrival of an optical signal at their inputs due to the inevitable difference 1: and 1 length

The optical paths are different, one of them forms a potential before the other.

In the node 2.1, the photodetector 7.1 first generates an electrical signal that goes to the control input of the node 2.2, the first output of the coupler 3.2 of the node 2.2 begins to close, and its second output to open slightly. The intensity of the optical signal at the input of the photodetector 7.2 of node 2.2 decreases, therefore, the potential of its output electrical signal to the electrical input of the coupler 3.1 of node 2.1 decreases.

Subsequently, at node 2.2, the first output of the coupler 3.2 is completely closed, as a result, an optical signal 1) is generated at the optical output, and a zero potential (O) is produced at the optical output,

At node 2 of 1, since zero potential is applied to the electrical input of the coupler 3.1, there is no optical signal at the optical output (O), and potential (1) is generated at the electrical output,

Let the potential be fed to record information at the input of node 2.1. In this node, the first output of the coupler 4.1 is closed, and its second output opens, the optical signal at the input of the photodetector 7 becomes zero, therefore, the electrical potential of the coupler 3.2 of the node 2.2 receives a zero potential. In this node, the first output of the coupler 3 opens, the input of the photodetector 7 receives an optical signal. From the output of this photodetector 7, the electrical signal is fed to the electrical input of the coupler 3 node 2.1. In this node since the moment the signal is input to the recording entry after: delay time. line 5 of the delay at the optical output is formed 1 /

The switching time of the controlled taps is no more than 7, the maximum speed of the photodetectors 500 PS, therefore, the duration of the information recording cycle

does not exceed 15 no.
