A device for determining interquantile latitudes operates as follows.

It is known that the area bounded by the differential distribution curve is proportional to the total measurement.

Interquantile and interdenil latitude is the distance between the quantiles of order and 1 / 10- -9 / 10, respectively. Quartiles, deciles divide the area, the curve into four and ten equal parts. When measuring interquantile chirpages, it is necessary to measure the distance between the first and third quarters, and when measuring interdecy latitudes, between 1 and 9 deciles.

The distribution curve is deployed over time and integrated, the voltage from the integrator output is stored in the memory blocks and compared to the voltage at the integrator output on the next clock cycle. The voltage on the storage units is supplied through resistor voltage dividers, the transmission coefficients for the voltage of which are equal: 1/4; 3/4 - when calculating interquantile and 1/10; 9/10 - when calculating the interdecyl latitudes.

At the moments when the voltage from the integrator output is equal to the voltage on the memory block: ke, the corresponding null indicator works. At the end of the cycle, the integrator is reset to zero by the key 14. At the moments when the null indicators are triggered, the trigger 15 is turned off by the time-of-pulse converter and the key 17 is locked on the curve, viewed, and on the oscilloscope 18, narrow depressions appear, the length of time between marks is proportional to interquantile latitude.

Consider the operation of the device on the example of calculating the interquantile latitude. In the first cycle, the storage units 11 and 12 memorize a voltage equal to 1/4 and 3/4 of the voltage at the integrator output at the end of the cycle. On subsequent cycles, the null indicator 5 is triggered when the first quartile is reached, the trigger 15 is thrown into one state, opening the valve 19, the pulses from the generator 21 arrive at the counter 20, and the key 17 briefly closes through the OR 16 circuit, making a narrow mark on the oscilloscope screen. The zero-indicator 6 is off. When the third quartile is reached, the trigger is reset to zero, the valve is closed, a number proportional to the inter-quantile latitude is recorded in the counter, the second mark will be displayed on the oscilloscope screen. The input converter is made according to the well-known scheme, and the input voltage Ux is proportional to the proportional time interval, the storage device can be implemented as a delay line on the shift registers or in another form.
