Description

one

The invention relates to the field of electronic modeling and can be used in the construction of hybrid computing machines and systems.

Digital functional transducers and generator functions are known for use in digital control circuits and digital differential analyzers.

However, they cannot be used when encoding information in corresponding time intervals.

The aim of the invention is to construct a device circuit for the functional conversion of the values specified by proportional time intervals, which would be compatible with the device circuits using 1 Co-1 registT | count structures.

With this slit in the proposed transducer, the counting inputs of the argument counter, the c-meter | functions and clock inputs of the two shift registers are connected via the corresponding coincidence circuit with the unit output of the formation trigger. The time interval for which the unit input is the control input ycTipuuCTBa the output is connected to the output of the counter of the document; the free input of the circuit coincides — and, connected with the argument argument, is connected to the output of the clock pulse ire, the free input of the coincidence circuit associated with the function counter is connected to the output of the first shift register; the free input of the condominium scheme associated with the shift registers is connected to the output of the shift impulse generator, and the output of the second shift register is connected via a counting rapper to the reversing control input of the operation counter.

Diagram of the device is shown in. Drawing. It consists of the argument counter /, the counter of function 2, shift registers 3 and 4, coincidence circuits 5-7, trigger forming the time interval of argument 8, counting three gages 9, clock generator 10 and shift generator //.

The device is intended to reproduce the single-valued functions of one independent-time function.,

The argument counter / is connected to the generator 10 through the coincidence circuit 5. The second input of this circuit is connected to the output of the trigger 8, to the input of which the output of the counter of the ar.gument / is connected. Two annular shift registers of 3 to 4 are synchronized for the clock power supply and are connected via generator coincidence circuit 7 to the generator (I). The output of one of the registers 4 through the coincidence circuit 6 is connected to the IK counting input of the function 2 counter. The output of the second register 3 through the trigger 9 is connected to the reversing control input of the function 2 counter.

The free inputs of the matching circuits 6 and 7 are also connected to the output of the trigger 8, one of the inputs of the KOToiporo is control.

| The device works as follows.

The count of pulses is preliminarily inserted into the argument counter, which complements the argument value up to the total capacity of the counter. A trigger control signal is applied to the input of the trigger 8, which sets the trigger in the single-state state and opens the matching circuit 5. The argument counter / starts to be filled with pulses of the clock frequency generator f. In this way a time interval is formed, during

which trigger 8 is the output in the single state and during which the counter of function 2 is filled. The counter input of this counter receives pulses from the output of shift register 4. The frequency of these pulses is variable and must correspond to the module of the reproduced function. Accounting for the sign of the derivative provides the second shift register 3, where pulses are recorded, the phase position of which corresponds to the moments of change of the sign of the derivative of the reproduced function. These pulses, the inputs to the counting input of the trigger 9, switch it and control the activation of the addition or subtraction mode of the counter of function 2. The initial value of the function must be recorded in the counter of function 2 before the onset of the working cycle in the form of a proportional number of pulses.

Thus, after the end of the working cycle, the counter of function 2 will contain the number of pulses equal to

-EL:

, + f signf df (x). about

The restoration data flow designer does not show the whole cycle.

The type of function implemented by the system | Stvom funktsii completely determined by the density of pulses recorded in annular shift registers. Instead of the latter, dynamic delay lines can be applied. However, in this case, the operation of the device should be carried out with synchronization from the side of the delay lines.
