Description

(54) A DEVICE FOR CALCULATING EMISSIONS OF RANDOM PROCESSES 3 is connected to the input of the unit to enable resolution of the summation. The block diagram of the device is shown in the drawing. The device contains black 1 threshold elements, n pulse formers 2, first element OR 3, reversible counter 4. block of resolution of summation 5 second element OR 6, pulse generator 7 and counter of code numbers 8. Block of threshold elements contains VI threshold elements, each output There is no no nicweH to the input of the formers 2, the first outputs of which are through element 3 OR are connected to the input. The summation counter 4 and with the first control input of the block 5 times the solution of summation. The second inputs of the formers 2 through the element 6 D / 1 and sv zashd with the subtraction input of counter 4 and with the second control input of the unit 5 whose signal input is connected to the output of the generator 7 pulses. The inputs of the unit 5 are connected to the outputs of the counter 4, and the outputs of its bits are connected to the inputs of the bits of the counter 8, the outputs of which are the outputs of the devices. The device works as follows. The measured signal arrives at block 1, which includes c-like elements, the response thresholds of which differ from one another by a given constant sampling, and their number is determined by a given measurement accuracy. The threshold elements form rectangular impulses normalized by the amplitude of the input signal with a duration equal to the time of the input signal (em threshold of the element). pulses received by them.The pulses corresponding to the leading edges from the first outputs of the formers 2 through the element 3 OR are fed to the input summed; counter 4, and the pulses corresponding to the back The fonts from (Second steps of these formers through element 6 OR are fed to the subtraction input of counter 4. In counter 4, the number of pulses received. Its summing input is continuously compared to 45 pulses sent to the subtracting input. The codes of the difference of these numbers go to block 5, which, according to signals from the generator 7, sends them to counter 8 for imumming with the code stored in it. To eliminate the recording of the code of counter 4 to counter 8, at the moments when a new code is installed in counter 4 of the control unit 5, pulses are applied from the outputs of the elements OR 3, 6, which prohibit the issuance of a code to the counter 8. As a result, at the end of the input signal, the counter 8 sets the code corresponding to the area of the measured signal. Since the interval between the thresholds and the summation of the codes for the current differences in the proposed device can be chosen extremely small, the accuracy of the proposed device is much higher than the accuracy of the known devices. In addition, the proposed device has a higher speed, since there is no operation in it to convert the amplitude of the input signal into a code that requires additional time. . FORUMULA and 3ETEN Device for calculating the emissions of accidental emissions, containing a counter of code numbers, the inputs of which are connected to the corresponding outputs of the resolver of the summation, the outputs of the counter of code numbers, the output of the threshold elements, the block of threshold elements, the unit of threshold elements of the code number counter, the output of the counter of code numbers pulse-shifting and shifting register, which is due to the fact that, in order to increase the accuracy of operation and speed, a reversible counter is entered into it, about pulse shapers, two elements OR} while the inputs of each driver pdklyucheny pulse to the corresponding output unit threshold elements whose input is an input device; the first outputs of the pulse shaper are connected through one of the OR elements to the summing input of the reversible counter and to the first control input of the summation resolution block; second shaper outputs

through another OR element, they are connected to the subtracting input of the reversible counter with the second control input of the summation unit, the inputs of which are connected to the outputs of the reversible counter, and the output of the pulse generator are connected to the signal one. input block resolution summation.
