Abstract

The invention relates to a measurement technique and can be used to create instruments with a light scale and in information recording systems on a photosensitive medium. The aim of the invention is to increase the speed and reliability of the device. The device contains a code converter 1, a registration block 2, a group of elements OR 3, and a group of elements M 4. The encoding method used allows, at the same width of the input codes, to reduce the number of elements in converter 1 and the number of registration elements in block 2, as a result the possibility of using a registration unit with a smaller number of elements with an increase in the width of the input information. 2 Il.

The invention relates to measuring Neu-technique and can be used to create instruments with a light scale in information recording systems on a photosensitive medium.

The aim of the invention is to increase the speed and reliability of the device.

Fig, 1 shows a functional diagram of the device; Fig. 2 illustrates the implementation of the device for the case of a four-bit input code.

The device contains a converter 1 codes, block 2 registration, a group of elements OR 3 and a group of elements And 4.

The device (figure 2) contains the Converter 1 codes, block 2 registration, the first 3, second 4, third 5 and fourth b elements OR, first 7, second 8, third 9 and fourth 10 elements And, a group of elements OR 11 and a group of elements And 12.

Additionally, in Fig. 1, the positions 1., ,, (K + 1) are indicated by the information inputs of the device, positions 1 ... (p-1) ... n and (n + 1) .. (n + p) - inputs of the registration unit, where n + p is the number of optical elements in the registration unit, with p (n + 1).

Consider the operation of the device in the derivation of the numbers 1 i n and n j (n + p). To output the number I to the inputs of the device, its code equivalent is supplied, including the potential of a logical zero to its (K + 1) -th input. Converter 1 transforms the signal supplied to it into a code combination 00 ... 011 ... 1, containing units. This code combination enters the second inputs of the elements OR 3 and AND 4. As the potential of the logical zero is supplied to the first inputs of these elements, the code combination 00 ... 011 ... 1 is set at the inputs of block 2c 1-st to n-th containing t units, and at the inputs from (n + 1) -th to (n + p) -th, the potential of a logical zero is established. This leads to the excitation of i elements of block 2.

To output the number j to the inputs of the device, its code equivalent is supplied, including the potential of a logical unit to the (K + 1) -th input. Converter 1 transforms the input signal into a code combination of the form 00 ... 011 ... 1, containing (j-n-1) units. At the outputs of all the elements OR 3, the potential of the logical unit is established, and at the first inputs of the elements AND 4 and their outputs - the combination 00 ... 011 ... 1, containing Q-n-1) units.

Thus, the inputs of block 2 from the first to (n + 1) -th are the potentials of a logical unit, which leads to the excitation of its (n + 1) elements. From the outputs of the AND 4 elements to the inputs of block 2, a code combination is received containing (j-n-1) units, which leads to the excitation of more (j-n-1) elements. Thus, as a result, j elements of converter 2 are excited.

The device is implemented with a block 2 containing 16 optical elements (figure 2). The information to the input of the device is supplied in the form of a four-bit binary normal code (r + 4). The device is implemented on 11 two-input OR elements and 11 two-input I. Elements. Block 2 includes 16 LEDs with a drive current driver.

The number of predictive elements required for the technical implementation of the proposed device, with three information inputs for the eight element registration block, and for the prototype of the Z31 18.
