k)) drift zero 2. Corrected signal Ux is fed to the first voltage converter - frequency 3. At the same time) 1110 the same signal is fed to the subtraction unit 4 of the current value of the signal from the reference voltage and. At the output of the subtraction unit, a 1p1-intensive signal Uo ,, - .vi is yu1 appears, a mirror image of the input corrected signal relative to the axis b ,,,, 2. An inv) signal is fed to the input p / mountain and) a voltage-frequency collector of 5 with a slope and transformation of s.

The relation between the steepness of the converters 5 and 3 is determined by the dependence A /; 52/5 10- + Yu-. Support iair bride

In this case, the output of the converter is the 5th base signal and the output level is close to the maximum. When passing through an iike, this signal rushes to the bullet. After being smoothed by a digital filter 6, this signal is output to the input of the peak selector 7 and the digital and hbiii converter 14.

The function of the Inca selector includes determining the beginning and end of the peaks. A digital-analogue converter is used to generate a compensating beam to set the correct zero drift drift correction.

At the signal of the Inca selector 7, at the beginning of the route, at the same time, Mmators 8 and 9 are switched on simultaneously. In the sumattor 8, 1 is formed 1, postuayuyi, and from the converter 3, and in the adder 9 --- from the converter 5. The accumulation of information goes to Those who are not selected by the iikik selector do not submit a message about the commando.

If the sign of the inverted signal from the output of the block is read 4 is positive, i.e. oii-f., By the decrimmer of sign 11 BI The permission is given to read the readings of the adder 9 by the arithmetic unit 12 and the reading of the readings and indications of the adder 8 is prohibited.

Thus, the area of the PPCs, whose amplitude is smaller than U ,, m, is determined by the adder (8 for the frequency of the converter 5, whose conversion slope is one times higher than the slope of the converter 3. The area of the peaks, whose amyllitude is greater than UH, is determined by the adder 8 by frequency converter 3.

Drift Correction The baseline pool is produced all the time until the start of the current baseline value. In other words, the tracking of the position of the baseline and its change. In time, it is done continuously until the beginning of the peak. At the beginning of the peak digital-to-analog converter

records the initial value of the baseline and keeps it to the end of the nickname. The zero correction at this time is carried out by the value of the PPIO, and the output of the memory in the memory. At the end of the nickname, this value is rewritten into the usb unit of the block 12 and a new correction of the baseline is made. The value of the base line, corresponding to the end of the i-ka, is arithmetically placed in a block. From these tributes, as well as to the data obtained from adder 8 or 9, the arithmetic unit calculates 11.:1on1, and the component’s endtitration produces separate components. The results of the analysis are provided to the recording unit 13.
