Claims

20 The goal is achieved by the fact that the pulse selector contains the pulse frequency of the reference frequency, the output of which is connected to the first inputs of the valve and the prohibition element 398, the second inputs of which are connected to the input bus, the register, the coincidence element , the second prohibition element and the trigger whose input is connected to the input bus, and the output to the first input of the second prohibition element, the second input of which is connected to the output of the first prohibition element, and the output to the first input of the register The output of which is connected to the first input of the coincident element included at the output of the device, the second input of which is connected to the first output of the pulse counter, the second output of which is connected to the second input of the register, a recalculation unit is inserted that is connected between the second output of the pulse counter and the second input register house. The structural electrical diagram of the pulse selector for duration is shown in the drawing. The pulse selector includes the pulse frequency generator 1, the gate 2, the first prohibition element 3, the pulse counter 4, the register 5 trigger 6, the second prohibition element 7, the variable multiplying or dividing unit 8 of the adjustable-frequency pulses, the coincidence element 9. At the same time, the generator of 1 pulses of the reference frequency through the valve 2 and the prohibition element 3 is connected respectively to the counting input and the output of setting zero and rewriting the number from the counter C of pulses to the register 5. The input bus of the device is connected to the control inputs of the valve 2, prohibition element 3 and the counting input of trigger b, the output of which is connected to the control input of the prohibition element 7, another input of which is connected to the output of the prohibition element 3, and the output to the first input of the setting to the zero position of the register 5, the second input of which is connected a cutting block 8 with adjustable coefficient with a second counter output i. The first and second inputs of the element 9 are connected to the first output of the counter C and the output of the register 5. The pulse selector operates as follows in duration. In the initial state, in the absence of input pulses, the valve 2 is closed, and the trigger 6 is in a state that ensures the open connection of the inhibition element 7. In this case, the pulses of the generator 1 through the open elements 3 and 7 of the prohibition enter the zero-setting circuits of the counter k and the register 5 and keep them in the zero state. At the output of element 9, there is no signal. At the moment the first pulse arrives at the device input bus, the valve 2 is opened, the prohibition element 3 is closed, and the trigger 6 is set to close the prohibition element 7. After that, the pulses from the generator 1 are fed to the input of the counter t and are counted for the duration of the first pulse. After the end of the input pulse, the valve 2 is closed, and the prohibition element 3 is opened and the result of the pulse counting of the generator 1 through the open prohibition element 3 is rewritten from the counter k to the register 5 via the recalculation unit 8, which operates either in the multiplication mode or in the pulse frequency division mode multiply or divide, which is regulated. Generator impulses 1 counter. Z is set to zero. Since the prohibition element 7 is closed, the pulses of the generator 1 are not fed to the input of the collection of the register 5. As a result, the register 5 records the number that is higher in the first case, in the other case less than N times the pulses counted by the counter k. When the next input pulse arrives, the valve 2 also opens, the prohibition element 3 closes, and the trigger 6 is set to the open state of the prohibition element 7. However, register 5 is not reset to the zero state, since there are no pulses at the output of prohibition element 3. Through the open valve 2, the counter C counts the pulses of the generator 1, and at the moment when the counter code C and the register code S are the same, the output of the element 9t which is the output of the device appears a signal indicating either exceeding or that the duration of the next pulse is not less than the duration of the previous pulse N times. 59 After the end of the next pulse, the device returns to its initial state, with the counter and register 5 being generated by the generator 1 pulses through the open inhibiting elements 3 and 7 to the zero state. The use of pulses in the proposed selector according to the duration of a conversion unit operating in the division or multiplying frequency of the pulses allows expanding the functionality of the device and obtaining information about the duration of the next pulse compared to the previous pulse. 1 Claims of the invention Pulse selector for the duration of aut.
