Description

The invention relates to automation, can be used, for example, in information recording systems and is a device according to the author. St. No. 1275491.

The aim of the invention is to improve the speed of the device.

FIG. 1 shows the device function of the device; on league. 2 - a, b are time diagrams of the input and output signals of the level converter, respectively.

The device contains an additional line 1 with a dotted lottery receiver 2, a signal level converter 3, composed of matrixes from a matrix 4 (miM) (m-1) of switching cells 5, a group of 6 elements And 7, an element And 8, a light source 9, the main line 10 with point photodetectors 11; and block 12 of signal coding. Switching cells 5 contain the first and second elements And 13 and 14, the reference photodetectors 15 and 16 of the main 10 and an additional 1 lines.

Pa Lig. 2 shows the curves for i-HI ix signals 17 and 18 and one sieve. a 19

Vstroystvo works as oi-time.

The optical signal from the pINE, which represents the process, is projected onto an up to 1 line of photo-receivers in 2.

If the luminous flux 18 hits the reference Lotto receiver 1G, it is fed to the control points of the commuting cells 5 of the first stop, which ensures the transmission of the input signal 17 to the first output of the cells S, and hence to the input of the corresponding A / 11 receiver of the main line 10. From source 9 A light optical signal is applied to the input of the reference photodetector 16 and to the first inputs of the AND elements of the group. If the light flux 18 hits, for example, the second photodetector 2 of the additional ruler 1, then the second cell 5 of the first column of the matrix will be a comm (L

read the n, i information input of the cell 5 of the paired stopset, from the output of which it will be fed to the second input of the second element And 7 of the group, from the output of which it is fed to the control inputs of the cells 5 of the third column. Let the input signal 17 (gets to the input of the K-th photodetector of the complementary ruler. Since the inputs of the cells 5 of the first and second columns have zero control signals, then with the K-th cell of the first column and (K-1) -and the second column, it will be fed to the information input (K-2) of the third party cell), on which the control signal from the second element of group 7 is fed, so it will be connected to the input (K-2) -th photodetector 11 of the main ruler. By block 12, the signals from the inputs of the photodetectors 11 are converted into corresponding codes and fed to the output of the device. By introducing a signal transform to the input of the main wave, the signal is given reduced relative to the reference signal.
