moreover, the duration of the pause between the first Bbw and the second, pulses is 2tcp and between the second and third.

Simultaneously with the arrival of the first pulse, an optical signal is fed to the input bus 8 to the second photodetector 4 of the first bit 1, module. Transistor 2 is turned off and positive feedback is triggered, which is implemented on the first photodetector 3 by emitting light from the light emitter 6. During the time, the first discharge of module 1 is excited.

As soon as the light emitter 6

The resistor 10 of this bit 1. and its collector have a high level of positive potential, which is fed to the second terminals of the second photodetectors 16 of all bits 13,13, ..., 13m of the third additional module 12, and the light emitter 6 of the third bit 1 module supplies the optical signal to the second photodetector 16 of the first bit 13 of the third additional module I2j. After time t, the first bit 13 of the third auxiliary module triggers, which remains in the excited state until the second bit 13, ..., of this additional module 12h works.

A second-order light emitter 18 J supplies an optical signal to a third photodetector 17, a first discharge 13, a third additional 25 module 12, and a first photodetector 15 of its own discharge 13, and the transistor 14 of this discharge 132 is in the open state , and the first bit 13 at. this zeroed - 30 h.

Thus, at the end of the first pulse and at the end of the pause following it, the third bit 1 35 module and the second bit 13 of the third additional module 12 are in an excited state.

With the arrival of the second pulse, the fourth bit of the 1 module is excited and the third 1 is zeroed, and after it ends, the seventh bit of the 1 module remains in the excited state and the first bit 13 begins to be excited, the seventh additional module 12.

With the arrival of the third pulse, the third bit of the 133th seventh additional module 12y remains in the excited state, and goes into the excited state of the eighth bit of the 50th 1g module. At the end of the third pulse, the second bit 13 of the third

Excited second bit 13 of the third optional module 12,

carries the information that the first impulse has. duration., and pause, followed him,. i.e. the weight of each additional module indicates the duration of the pulse, and the excitable discharge in it indicates the duration of the pause following the pulse. The third excited bit 13, the seventh additional mode

l 12 carries the information that the second pulse has a duration of 4Tcr and the duration of the previous pulse is subtracted from the weight of the sequence of the excited additional module, and the pause following the second pulse has a duration. The ninth bit of the 1d module carries information that the last pulse has a duration of 21.

Thus, the module allows to determine the time parameters of any sequence of pulses. The advantage of an optoelectronic module is enhanced functionality and information capabilities, since it can handle not only single time intervals, but also their sequences and visually represent their time parameters. Tracks in the same sequence as they were received devices.
