Description

The invention relates to a measurement technique, in particular, to the construction of measurement result presentation units, 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 simplify the device.

Figure 1 shows the functional diagram of the device; FIG. 2 shows an example of a specific implementation for the case of a registration block containing 16 registration elements.

The device comprises (Fig. 1) a code conversion unit 1, a registration unit 2. the elements of OR 3 and the elements of AND 4 The device in FIG. 2 contains a code conversion unit 1, a registration unit 2, elements OR 3-13, elements AND 14-24. Additionally, position 25 marks potential bus 1

The device works as follows.

When you enter an even number i 2m. where m 1,2 .., k is the width of the input code, the code equivalent of the number i is fed to the information inputs of the device, and the control input is level O At the output of block 1, a code of the form 00 011 1 containing i / 2 units is formed. As a result at the outputs of the elements And from the second to the n-th, the (n-1) -the size of the bottom of the code combination is set to 00..011 ... 11, containing 0 / 2-1) units. At the output of the first element, And is the potential O and at the output n th element OR - potential 1 Thus, on the odd inputs of block 2, an n-bit of the code combination 011 1 is formed, containing i / 2 Trace units of course, as a result of the code equivalent of the number i, the registration element of the block 2 is excited at the information inputs of the device

When an odd number ji + 1 is entered, its code equivalent is supplied to the information inputs of the device, and level 1 is fed to the control input. The first elements of block 2 are excited like the case of number I, and the output of block 1 with the number (1 / 2 + 1) potential O is generated, which is fed to (I + 2) input of block 2, i.e. his (i + 2) and older registration elements are not excited. At the output of block 1 with the number (I / 2), potential 1 is formed, which arrives at the first input of the corresponding element AND, the second input of which receives 1 from the output of the previous element OR, which leads to the excitation of the (i + 1) -th element of the block 2. Thus, in block 2, I + 1 registration elements are excited.

Example. The device was implemented with block 2, containing 16 elements. Information on the input of the device was summed up in the form of a 4-bit binary normal code (r 4). The device is implemented (figure 2) on 11 two-input elements And 11, two-input elements OR. Unit 2 includes 16 LEDs with drive current driver.

The number of logical elements necessary for the implementation of the device is Sn 2r + 1 - 2 (r + 1), where r is the input code width, i.e. Sn 22.

To implement the prototype in this case, Sn g + 2r4-1 would be required, i.e. Sn 35 elements.

Thus, while maintaining the function of the device, the invention allows a reduction in the number of logical elements.
