Description

one

The invention relates to the field of computing technology and can be used as a universal element, optional: To assign various simple and complex functional 5 conversions of digital electrical signals, including modeling the properties of every six-shelf, arithmetic unit, digital integrator, generator special-shaped signals, etc.

The Code-Voltage type decoding function converters are known that contain an input register connected to the control inputs of a lyramid type switch that is connected to the output block 15 AND voltage or current sensors assembled on the weights-resistances. In accordance with the available transfer characteristic, they are capable of changing the carrier and signal information with a simultaneous change in its content.

The disadvantage of these converters, as computational elements, are:

the comparatively low accuracy of the computational operations performed, due to the fact that the output information carrier of the signal is analog (voltage or current);

.the ability to perform only simple functional transformations, due to the presence of one signal input; 30

the inability to quickly reorganize the parameters of the transmission characteristic, or the selection of the desired program of functional transformation in the operating state of the converter.

The aim of the invention is to develop a universal functional converter that performs complex functional transformations of the form "Code - Code.

The proposed device differs from that known by the presence of a generator of reference and digital signals (GCSS) and a second input register, sensors of electrical signals made controlled by digital signals.

The functional connections in the converter are as follows.

The output of the GOCC is connected to the-working inputs of the controlled sensors of electrical signals, the control inputs of which are connected to the outputs of the second input register, and the outputs are connected to the working inputs of the pyramidal (switch. The control inputs of the latter are connected to the outputs of the first input register, and the output is connected to the output block.

When constructing a converter of the type "Code - code, the programmable switch of the pyramidal type is contained in the composition of each controlled electric signal sensor

and master generators of constant digital signals. At the same time, the latter have inputs connected to the output of the GCS and outputs (connected to the operating inputs of software switches. The control inputs of the remote switches are connected to the outputs of the second INPUT register, and the outputs are connected to the signal (working) inputs of the pyramidal switch that controls inputs associated with the outputs of the first input register.

A code-to-analog converter is different from the previous one in that instead of master oscillators of digital signals it has weight resistances or potentiometers.

The output signal of the converter can be represented by serial or single and parallel codes. For this, its OUTPUT block contains a matching box, a register-converter of codes (serial or single code into parallel) and a control key used to ensure the integration of the output signal. Matching frame and register-converter of codes along the line - “Installation zero through controlled are connected to the GCS and input registers, besides that, the working inputs of the specified stages are connected to the output of the pyramidal switch.

The drawing shows a block diagram of the proposed device.

It consists of controllable sensors of electrical signals /, master generators 2, software switches of pyramid type 3, pyramid switch 4, output unit 5, matching stage 6, register-converter codes 7, control key 8, generator of reference and digital signals (HOC). ) 9, the second input register W and the first input register 11.

Depending on the purpose of the converter With 1PomO | Schu, the driving oscillators of controlled sensors of electrical signals are simulated a series of transfer characteristics that have an independent value or are functionally related to each other. In this case, the pyramidal switch property is used to connect to the output only that signal input that corresponds to the discrete digital value of the signal applied to its control input.

Each master oscillator is tuned to produce a signal delivered in a complex functional relationship to one or other possible discrete values of the input signals. In this simulation of the transfer characteristic, any input signals to the corresponding transducer input registers will be subjected to a simulated functional Transform.

Consider the operation of the converter for a particular case of performing a simple functional transformation of the form "Code - Code.

Let the first input signal x (li) be subjected to a functional transformation corresponding to the constant value of the second input signal U The transformation must meet the following mathematical expression:

2 (M b ().

where tk n-Ati p 1, 2, 3, ..., t.

It is known that the converted signal x (tfi) can take the following discrete values: Xi, X2, ..., Xm.

To provide a given functional transformed, a preliminary simulation of the transfer characteristic is performed by setting the corresponding parameters of the master oscillators.

With this, each master oscillator (/, 2, 3, m-th) connected to the output block with the signals yiXi, yiXm is tuned to output a constant digital signal corresponding to / i (i); fi (x2); / 1 (3);

fl (Xm).

In the working COS, the constant digital signal yi is fed to the input register 0, and the signal x (t /) to be processed is fed to the input register 11.

Let at some i-th discrete moment of time the value of the input signal x (t is equal to Xi. Before it is written to the input register (a pulse “Setting zero, which will reset the input and output registers and goes to the NDG. After a time interval Dt required for recording the number on the input register and establishing a working circuit to match the output signal, the NCC produces a series of bit

pulses that arrive at all master oscillators.

The first master oscillator J-TO of a controlled sensor of digital signals with input of its bit pulses produces the formation of a constant digital signal corresponding to the value fi (Xi}. Passing the software and Lyramid switches, this CONSTANT signal will be fixed on the register-converter codes

output block and pass through a matching stage to the output of the converter. Similarly, the formation of other discrete values of the output signal. It is difficult to note that if you make a simulation of the transfer characteristics of a converter and other possible values of the second input signal Y (T), simultaneous functional conversion of both signals and Y (T) is possible, including

number, functionally related to each other, the generation of electrical signals is a special case of electrical signal conversion, in this case a linearly increasing digital series is fed to the first input register. At the same time, the output of the converter will deploy a new numerical series, The resulting values are determined by the simulated transfer characteristic. If there are several modeled transfer characteristics, the choice will be determined by the input signal to the second input register. It is easy to see that due to the fact that each particular value of the output signal is determined by two signals, the considered converter can simulate the properties of any six-pole network. Inputs for receiving digital signals defined by a parallel code are considered as single.

In order for the converter to operate as an integrator, a sequentially repeating linear-incrementing digital series is required to the first input register, and a digital signal corresponding to the error signal is sent to the second input register. The latter will establish one or another transfer characteristic, each of which has its own increment value Orde nat, and, therefore, will correspond to one or another rate of change of the output signal.

It follows from the above that in the case under consideration the transducer should have a series of linearly increasing transfer characteristics.

High accuracy of the converter operation can be ensured due to the digital form of the input and output signals, Non-distorted information distortion when passing through the key elements of the switches, and not subject to drift phenomena.
