SU769549A1 - Device for determining differential extremum value probability distribution law - Google Patents

Description

The invention relates to the field of computer technology for the analysis of statistical data and can be applied for the study of endurance con, structure: flying vehicle.

Devices are known that contain a-m- and уд selector selectors, formers, whose inputs are connected through the corresponding a-m-select selectors to the input of the device, and pulse counters.

The known devices have a low accuracy of 1aliza- tion due to the fault introduced by differential amplifiers and used in these devices.

In addition, the noise immunity of such devices is insufficient, since in the case where the polarity of the interference pulses and the information pulses do not match, the device can react to the interference pulse, which causes two pulses to be recorded in the counter in the absence of an extremum.

The presence of a certain delay in the operation of the control nodes limits the upper frequency of the analyzed voltage, and this loss depends on the magnitude of the selected delay.

The aim of the invention is to improve the accuracy, noise immunity and expansion of the field of application of the device.

The goal is achieved by the fact that D the proposed device is inserted into a pulse distribution unit, the inputs and outputs of which are connected respectively to the outputs of the drivers and the inputs of the pulse counters.

The pulse distribution unit contains a source setting switch AND for each channel a trigger with

10 counting input, trigger, elements AND, OR, inverters. A single trigger output with a counting 1 input in each channel is connected to a single trigger input, a single output of which is connected to the first input 15 of the first element AND, the second input is connected to the trigger inputs with a counting input and is connected to the input of the unit. The zero inputs of the triggers and triggers with the counting input through the OR elements are connected to the initial state setting switch, through inverters with the corresponding inputs of the block. The first inputs of the second and third elements And in each channel, except the first and last,

25 are connected to a single trigger output, the second inputs are connected respectively to the outputs of the First elements AND the subsequent and previous channels, the outputs through the OR element are connected. with appropriate

 block output. The first and last outputs of the block are connected respectively to the first and last inputs of the block.

The unit of distribution of impulses to the reaction, em, only impulses of positive polarity and. Transmits the impulse to the corresponding counter only. If there is a certain code 1Q01M1binaTsION of three pulses, and its inputs, a / frequency diaa-azone of the analyzed voltage is limited only by the speed of the elements.

The device diagram is shown in FIG. 1, and the distribution pattern of pulses is on phi-g. 2 .:

The device, for example, on five quantization levels, contains amplitude selectors 1-5, (shapers, blocks to // distribution of pulses, pulse counters 12-16, and input / 7 devices.

The pulse distribution unit contains elements AND IS-26, elements OR 27-34, inverters -35-40, triggers with a counting input 41-45, elements AND 46-57, and an initial state setting switch 58. Elements AND 20, S, 25, 26, 47, 48, 50, 51 and 55, 56 impurities (enen for building triggers.

The device works as follows.

The input signal is fed simultaneously to the inputs of the amplitude selectors of all ka. On the catch, the output of which forms the voltage drops and three times, and if the input signal exceeds the value of the reference voltage of a given quantization level applied to the inputs of the amplitude selectors. The voltage drops arrive at the formers, which generate impulses of a positive field and a duration equal to the time spent being calibrated along the voltage in this differential corridor.

The determination of extremes is made by methods based on fixing a change in the sign of the increment of a function. (After converting a continuous fusion | amplitude selector into an impulse voltage, all subsequent operations are performed by an impulse distribution unit with discrete values. When a pulse arrives from the former, for example, the level per channel of the O.N is set. trigger (elements 55, 56) through trigger 43 with a counting input to the single state, and resolution is input to the input element I 54. The next impulse arriving at the subsequent channel sets the triggers in the same state as triggers. Kana A / C. If further change of the signal pulse appears at the input K + channel 2, then channel triggers / C are set to the initial state via the inverter 39, and the channel kmpulszapo- minaets.

If the third AND-pulse appears at the input (channel K, then it is through elements 54, the element AND 22 id element OR 29 gets to the output of the channel and to the counter of the given channel.

When reducing the analyzed voltage, the device works analogously. The operation of the first and last channels differs from the operation of the other channels in that the impulse from the input of these channels falls into the counter directly to the pulses. If before that there was an extremum in the second or penultimate channel, then the pulse from the first or last channel goes to the input of the counts of the pulses of the second or second to last channel.
