Description

The invention relates to automation and computing, in particular to devices for calculating numerically the ratio of time intervals. A device for calculating the time interval ratio, including reHepaTqj pulse elements AND OR and NOT, one-shot, counters, and code block ij, is known. It is also known a device for calculating the ratio of time intervals, pulse trigger generator, pulse shaper, and AND and OR elements , one-shot, counters and block comparison code L2J. The disadvantage of these devices is the reduced accuracy of the calculation of the output of a result rounding error, the maximum value of which is equal to the value of the divider. Closest to the proposed. is a device for calculating the ratio of time intervals, containing a reference frequency generator connected by the first extruder to the first input of the first element AND connected by the second input to the first input of the device, the input of the first one-frequency circuit and the input of the element HE, and the output to the input of the first counter, connected to the bits of the outputs to the installation inputs of the second counter, connected to the control input of the installation code with the output of the first OR element, and the counting input with the output of the second AND element connected by the first input one output to the .element output is NOT, and the second input to the second input of the device and to the input of the second one-vibrator, the output of which is connected to the first input of the third AND element connected by the output to the first input of the second OR element connected to the output of the result counter, the second input with the trigger output and the first input - with the output of the first one-shot, the setup input of the trigger and the first input of the first OR element connected by the second input to the overflow output of the third counter, connected by the counting input with the output And, and the bit outputs - with the first group of input-block comparison code, connected to the second group of inputs to the bits of the second counter, and output to the counting input of the trigger connected to the second input of the third element 4872V of its element I, the third input of the second element and is connected to the first output of the reference frequency generator | d. The disadvantage of the prototype is constructive complexity. The purpose of the invention is to simplify the arrangements as well. The goal is achieved by the fact that the device for calculating the ratio of time intervals, containing a reference frequency generator, connected by the first output to the first input of the first element AND, connected by the input to the first input of the device, the input of the first one-vibrator and the input of the element, NOT, and the output from the input of the first counter connected to the bit outputs to the installation of the second counter, connected by the control input of the installation code to the output of the first OR element, and the counting input to the output of the second AND element, under The first input to the output of the element is NOT, and the second input to the second input of the device and to the input of the second one-oscillator, the output of which is connected to the first input of the third AND element connected by the output to the first input of the second OR element connected to the output of the result counter, the second input - with the trigger output, and the third input - with the output of the first one-shot, setting trigger input and with the first input of the first element OR, the second output of the reference frequency generator is connected to the third input of the second element, And The output of the second counter is connected to the second input of the first OR element and to the counting input of the trigger, the output of which is connected to the second input of the third element I. The drawing shows a block diagram of a device for calculating the ratio j eMOHHbix intervals. The device contains a generator 1 operatic; astrota, connected by the first output to the first input of the first element I 2, connected by the second input to the first input of the device, the input of the First one. Vibrator 3 and the input of the element HE 4, and the output - to the input of the first counter 5 The bits of the bits of the counter 5 are connected to the installation inputs of the second counter 6 connected by the control input of the installation code to the output of the first element OR 7, and the counting input to the output of the second element AND 8. The element 8 is connected by the first input
