Description

The invention relates to automation, computer engineering and can be used in synchronization systems, decision circuits of composite signal receivers with redundancy.

The purpose of the invention is the expansion of the scope of the device by increasing the value ’of the input signals.

The drawing shows a functional diagram of the device.

The device contains decoders 1, blocks 2 converting a binary unitary code into a full binary code, each of which is made on a digital-to-analog converter 3 and an analog-to-digital converter 4, a switching unit 5 made on blocks 6 of keys 7, '8 and a decoder 9, elements OR 10, inputs 11, 12 and outputs 13-16 of the decoder 1, inputs 1719 and output 20 of the digital-to-analog converter 3,. as well as outputs 21, 22 of an analog-to-digital converter. .

The device operates as follows.

I

Consider the operation of the device by the example of the analysis of the structure of a complex signal, consisting of p = 3 elementary (non-binary) signals, each of which is represented with = 2-digit binary code combination.

Table 1-3 explain the conversions performed by the decoders 1, digital-to-analog converters 3, and analog-to-digital converters 4, respectively.

Let a complex signal of the form 00 00 00 be received at the information inputs of the device. The first (left) elementary non-binary signal 00 is fed to the inputs 11 and 12 of the 1 ^ decoder. The second and third elementary signals 00 and 00 are fed to the corresponding inputs of the decoders 1 _a and 1j. In accordance with Table 1, decoders 1 convert the input elementary signals, a single signal is formed at the upper outputs of each of them. The signals from the outputs of the decoders 1 are fed to the inputs of the code converters 2, the operation of which is explained in Table. 2 and 3. Since the input signal of the converter is 2 ^ - 111, signals are generated at its outputs 21 and 22

11. For the remaining converters 2, the input and output signals are zero. ,

Of great importance is the type of signal at the control inputs of the device. If the binary combination 00 is on these inputs, then keys 7, 8 of block 6 <are opened, if signal 01, then keys 7, 8 of block 6 ^ are opened, signal 10 opens keys 7, 8 of block 6d, and signal 11 - keys 7, 8 block 6 ₄ .

Let the binary code signal 00 be present at the control inputs of the device, in this case the keys 7, 8 of the block 6 <are opened and the single signals from the outputs 21 and 22 of the converter 2 ₄ pass through the OR elements 10 ₄ and 10 ^ respectively to the device outputs. The code combination 11 at the outputs of the device. Shows the number of elementary signals 00 (it is about this signal that information was requested on the control input) in the input complex signal.

Let a complex signal 01 01 01 appear at the information inputs of the device, and 01 at the control inputs. At the outputs of 14 decoders 1, and 1 ^, a single signal is formed, at the output of 15 decoders C is a single signal.

Single signals from outputs 14 appear at the inputs of the converter 2 ^, from the output of which binary combination 10 is removed.

The combination of 10 at the control inputs leads to the formation of a single signal at the output of the decoder 9, which is connected to the control input of the block 6 ^ keys, and the output combination 10 of the converter 2 _g passes to the outputs of the device.

Thus, at the outputs of the device in binary code, a signal is generated corresponding to the value of such an elementary signal in the input complex signal, the binary code of which is supplied to the control inputs of the device.
