Claims

Generator 1 is connected to the input of divider 2, the outputs of which are connected to the corresponding inputs of multiplexer 3, the installation inputs of the latter are connected via register 4 to input 9, the output to the first input of element 5, the second input of which is connected to output 10, which is connected to the trigger output 6. The output of element 5 is connected to the counting input of the counter 7, the installation inputs of which are connected to input 9, and the output connected to the first trigger b, the second input of which is connected to input 8. The device operates as follows. . . The pulses of the oscillator 1 of the reference frequency Td are fed to the input of the divider 2, the outputs of which generate frequency signals associated with the reference frequency by the following ratios D. 1 10 Frequency signals Pj, Tg, .-- and enter the information inputs of the typlexor 3. The output of multiplexer 3 passes a frequency signal defined by a code recorded in the register at the command input 9. Trigger b, which element 5 opens, is set to one state by the trigger signal / input to input 8. The frequency signal from the output of the multiplex The exora 3 is fed to the input of the counter 7, into which the code on input 9, which is proportional to the time interval, is preliminarily entered. The time interval, fop and direct and output 10, is determined depending on the contents of register 4 as follows. M is 10, where p is the contents of register 4; 5.- counter contents 7. The maximum time interval of a mole that can be formed at. the given reference frequency f in this case is written in the following form: T G -2 dcais where Rutz is the counter size 7; Pp is the register size 4, Thus, to set the maximum time interval, a smaller register size is required — thanks to the rapid growth of function 10. This achieves a reduction in the control word cad bit, simplifies the device and reduces the memory capacity of the processor. The invention includes a time interval shaping device comprising a reference frequency generator, the output of which is connected to the counting input of a frequency divider, a match element, the output of which is connected to the counting input of a time counter, and the first input of the match element is connected to the trigger trigger output, the setting inputs of which are respectively connected to the triggering input of the device and the output of the time interval counter, the setup inputs of which are connected to the command inputs of the device, and the scale register Aba, characterized in that, in order to increase the reliability of the device in operation, a multiplexer is inserted into it, the information inputs of which are connected to the corresponding outputs of the frequency divider, the multiplexer output is connected to the second, the coincidence element input, and the multiplexer installation inputs are connected with the command inputs of the device through the scale register.
