The invention relates to the field of measurement technology, in particular to the KOHcTpvKiyin of the results presentation and measurement nodes, and can be used to create instruments with a light scale and in information recording systems on a photosensitive medium.

The purpose of the invention is to increase the reliability of the device.

Figure 1 shows the functional diagram of the device in Figure 2 - the same for the case of using a four-bit input code and a registration block containing 16 elements of the register information.

The device (Fig. 1) contains the first 1 and second 2 code converters, the registration unit 3, the block of elements 1, 4, the block of elements 5, the Index m (Fig. 1) denotes the size of the first code conversion block, the index n being the second converter codes.

The device (Fig. 2) contains the first 1 and second 2 code conversion blocks, registration block 3, three groups of elements OR 4, three groups of elements AND 5, elements OR 6 and 7, elements AND 8 and 9. Position 10 denotes the potential line Log .one,

The device works as follows.

When entering the number (m + 1) + b to the inputs of block 1, the code equivalent of the number bim is given, and the code of the number atn is fed to the inputs of block 2. As a result, at the outputs of blocks 1 and 2, coding combinations of the form 00 ... 011..1 are set, containing, respectively, b and a units. From the outputs of block 1, the code combination enters the first inputs of the OR 4 elements and the first inputs of the AND 5 elements of the first group. From the outputs of block 2, the code combination is fed to the second inputs of the corresponding elements AND 5 and OR 4 groups and to the inputs of block 3 with the numbers p (t + 1) 3, where ..a.

As a result, the registration elements of block 3 with numbers are excited, t-bit code combinations 11 ... 1 are set at the outputs of the groups of elements OR, the t-bit at the outputs of the (a + 1) -th group of elements OR are set code combination 00 ... 011 ... 1, containing b units. This causes an install.

at the outputs (a-1) of groups of elements AND t-bit dngh code combinations 11 ... 1 and t-bit code combination 00. . .011 ... 1, containing b units at the output of the a-th group of elements I. From the outputs of block 2, the last group of elements ШШ 4 and a groups of elements И5, the specified code combinations are fed to the inputs of block 3, as a result of which a (t +1) + bh its elements.

Example. The device is implemented in conjunction with block 3, performed on 16 registration elements (Fig. 2). Information to the device input is supplied in the form of a four-bit binary normal code (). The device is implemented on 11 two-input OR elements and 11 two-input I. Elements. Unit 3 includes 16 LEDs with drive current generator. The number of logical elements necessary to implement a known device, i.e. . In the case of applying the invention, 3 ,, -2 (g + 1), i.e. Sn 22.

Thus, in the case of the use of block 3 with the same number of registration elements, the proposed device contains on (3g + 1) -elements less than the known. Therefore, the reliability of the device is improved.
