SU258739A1 - STATISTICAL ANALYZER - Google Patents

Description

The proposed statistical analyzer is in the field of computing technology and can be used for statistical analysis and also in the quality control of some industrial products.

Known statistical analyzers performed on gas-discharge indicators with digital-to-analog converters, as well as on ordinary binary counters, are significantly complicated when calculating the distribution median.

Analyzers based on linear decatrons are also known.

The proposed device differs from the known analyzers in that, in order to simplify the device when calculating the median, the input of the reversible counter (the sample is connected to the output of the pulse generator, which is connected to the first and second subcathodes of the decatrons via a reversing switch, the first indicator outputs are connected via the input of the sample counter connected to the zero input with the control output of the pulse generator. The second inputs of each subsequent collective circuit are connected to zero indicator electrodes of the previous decatron, and the second of the first collecting circuit is connected

through a common switch to a source of constant voltage.

Information about the distribution is entered into reversible counters, which are made on linear decatrons, and in a reversible sample counter, the command for calculating the median is simultaneously subtracted from the linear decatrons representing the distribution,

one by one and from the sample counter.

When the number of subtracted pulses reaches half of the sample, the subtraction stops and the median is determined by the slit of the linear decatron.

Scheme of the statistical analyzer shown in the drawing.

It contains linear dekatrony / (indicator-counters), collective schemes “OR 2, pulse generator 3, reversible sample counter 4 and non-switch 5.

Statistical analyzer works as follows.

In the initial state, on linear decatrons, the bit is set at the first indicator electrodes, and the sample counter is set to zero.

The switch is set to /.

Under the action of information signals arriving at the inputs of the OR circuit and the pulse generator in any Sequence (eg, the duration of the information sigals should exceed the duration of the sequence of pulses controlling the linear decatrons), the input of one of the decatrons opens, and the pulse generator produces two pulses arriving at control electrodes of an open decatron and a sample counter, recording the same number.

Upon reaching the required sample, which can be set in advance, the switch is set to //. In this case, the decatrons and the sample counter are prepared for the subtraction mode. The input of the blocking device of the sample counter is connected to the first indicator electrodes of the decatrons, the pulse generator starts to operate in a continuous mode, the OR circuit of the first linear voltage source is supplied, the sipnal, under whose action the decatron opens.

The pulses from the generator of pulses are fed to the inputs of the first decatron and the sample counter.

Occurs Subtract the numbers written in them. The subtraction from the first decatron occurs until the knockout is set to zero. After that, the signal from the zero indicator electrode is fed to the input of the OR circuit of the second linear decatron, the next day is opened, the subtraction of the numbers written in it begins, and so on until a number equal to half of the sample is subtracted from the sample counter.

After that, a signal is received from the sample counter to the impulse rerierator, which closes it.

At the time of the location of the discharge At the first decatrono indicator electrodes, the sample counter is blocked so that at this time there is no subtraction of the unit from the sample counter when subtracting from each

the linear decatron, as their initial and final states differ by "1 (the initial position is the first indicator electrode, the final position is the zero indicator electrode).

Subject invention

Statistical analyzer containing

switch, reversible counter-sampling, recursive counters-tips on linear decatrons, the first sub-codes of which are connected through collecting circuits to the sources of the impulse processes under study, characterized in that, in order to determine the statistical distribution median, the reversible counter of the sample counter is connected to the output of the pulse generator which, through a reversing switch, is connected to the first and second decatrons of the decatrons, the first indicator outputs of which are connected via a switch to the iruyuschim input sampling counter connected to the zero input of the control output generator "mpulsov; the second inputs of each subsequent collecting circuit are connected to the zero indicator electrode of the Previous Decatron, and the second input of the first collecting circuit is connected via a common switch to a source of constant voltage.
