Investigation from: carries to electric current processing current conductor m. Aggregals.

Corrective analyzers of the impulses for the O1Prosio electric cell of TaiHiKOB generate impulses of a single presence and current of VE (Route: O, proj-ejule,. F, I) Kti1V "YH impulses HeiBbrcoKa, as usually ammount there is a voltage across the leading edge, co.tor; a1I from working and fictitious pulses is different from each other.

The proposed alinal "gate" allows you to distinguish between 10 and 1 pulses of all the species indicated.

With this purpose, along the rear fryunt, the erosion gap and the formation unit and | MPulsov, a device is implemented, made as an integrating value on a parallel-connected capacitor and resistor, with a parallel-coupled semi-semiconductor zener diode connected to the wiring or a semiconductor and a zipper conductor and a semiconductor zener diode. connected to the transistor switch, the connection | NennO | Mu through the valve and the resistor to e (the ionization gap.

AJnaiLizaltop makes a comparison of the height of the rear axles of the impulses with the reference voltages, m1I. With the sinking height of the back dandy (see Fig. 2), the impulses refer to and: mp: M idle speed, with 2 to the working impulses, with - to fictish impulses and

Page | An ethnology | I scheme of the analyzer according to FIG. 3. To the interelectrode / mu gap 1 is attached a divider (s for resistors,

to which is connected a device for separating the falling edge and the pulses 4, tuned to the required frequency, which corresponds to the frequency of the pulse following from the pulse generator (not shown in Fig. 3). The device 4 emits pulses with amplitudes corresponding to the heights of the falling edges of the incoming pulses. The output of device 4 is connected to the separating circuit "OR 5, to which four channels of forming countable pulses are connected. Each channel transmits pulses of a certain amplitude, in accordance with, and the diagram of FIG. 2

Since the schemes of all channels are the same, tO

it is enough to consider the operation of one channel, for example the second. From 1M; p1M1Is impulse PSTUpEbt to the input of the circuit C | p.a | voltage 6-2 connected to the standard no. | M: at the source voltage Ik 7--2. When the output of the circuit 6-2 is allocated, a counting pulse is generated, which is formed using the yipp-relay 8-2 I1, then it goes to the separation circuit OR 9-2, and then to the AND; 10-3, to which The I1M1pullao.v counter is connected, for example, teel, and PS-: 100 (on fi1G. 3 it does not show). To the scheme “And 10-2 podyulyuchey also shemka- and“ di: cap 11i 2–2, it is represented by a current amplifier, loaded with an incandescent lamp, the luminous intensity of which determines the number of incoming I1M1puls1Ov. Schemes and matches “And 10-2 skips I1miulvo from a Kipp-relay 8-2 tiuyo in case when OTcynrcTBiyieiT is cryptic from the previous one (in the first case from the first) channel of the circuit1Ы“ OR 9-1, and drove off from the time relay : 12 through the separation circuit "OR, 13. Timer 12 is turned on with a button and sets the time interval during which the pulse analysis is to be performed.

The iHa output of the second channel is counted by a counting I1 pulse only in TOiM, if the time relay is turned on 12, and from the split circuit OR 9-1 there is no forcing signal, i.e., if. The impulse that passes through the second channel passes through: both TpeTbeiMiyi software and the fourth channel, but to the ochatchi: ka1M display no. &Amp; indication through the THESE channels, because each previous channel blocks the next one.

1PrIlNCi1PiLa schema.a device, highlighting the trailing edge of ififuls, is shown in FIG. 4. Voltage impulses: from the pulse generator 14, supplying the air flow gap 1, receive two Hai. divider | . The first of them consists of 2 HI 3 resistors, ai the second of pe3MCTOpOiB 15 and 16. First days: the zener diode 17 limits amplitude and mp pulses, and thanks to the condenser 18, T | reugol1 them are fed to the base of the semiconductor tr1 diode 19 , the duration of the co-delay delay relative to: And the front fronts AND M pulses of the generator are determined by the charge circuit of the capacitor 18.

From the output 22 are removed im1pulsy nayur hypotheses: toshko prI1 saKipbiToiM triode number 21 when supplied with working vmpulsy electrodes.

As already mentioned, the pulses from output 55 are sent to four channels. The channels have single circuits | Ы and differ in the level of the reference one | Therefore, only the second channel is considered further.

FIG. Figure 5 shows the schematic diagram of the channel I | Zmeren1I and. formation of happy pulses. The pulses go to the input valve 23 of the comparison circuit. At its output from the collector of the semiconductor triode 24, a voltage pulse is released in that sloan, if; amplitit; ud1 input impulse is equal to or greater than the reference voltage set by the variable resistor 25. This i-pulse through the capacitor 26 passes to the input of a kipp-relay on semiconductor triodes 27 and 28. The formed counting pulse passes to the coincidence circuit on the resistor 29, the capacitor 30 and the valves 3} to 32 to further to the counting output 55 and to the display circuit assembled on semiconductor T1riodak 34 and 55. However, the passage of a pulse is possible only at zero potential at the input 36. When: a counting pulse arrives at the triode base 34, the latter is unlocked, and the voltage at its set of relapses becomes equal to zero. This voltage is applied to the coincidence circuit of the next (third) channel through output 37, prohibiting the passage of counting pulses in this channel. In its turn, the previous channel (.first) at. DRIVING THROUGH through it, the pulse delivers zero hr. through the diode 38, blocking the second channel. If there is no counter in the first channel, then from the output of the BTOfporoi channel; impulses come on. counts K pulses. At the same time counting pulses fall on. the input of the current amplifier. on the semiconductor triad 35, the base of which is enclosed by the incandescent lamp 39.

Scheme time relay is presented on .fig. 6. Its charge / circuit is formed by resistipoiM 40 and a capacitor 41. The trigger device is assembled on semi-conductive triodes 42 and 43. The relay circuit includes a trigger on Semi-Primer tri-44 I1 45 Hi start circuit on resistors 46, 47, 48, capacitor 49 and a valve 50 with a start button 51. DI1 is pressed: and: 5.1 Tipnrrep buttons o) flips - triode 44 is closed, and T1p1 and 45 is opened. From the collector of triode 45 a signal is received that permits the passage of pulses from the channel: into the account of the dial. Valve 52 pulls off 0 | Tr. P. Offset offset. The capacitor 41 begins to charge through the resistor 40. As the voltages increase to the capacitors. 41 to the level given by the diodes (Zener.) 53 and, 54 cnycKOBiaiH the circuit is overturned, and: through a circuit, a capacitor 55 - a resistor 56 - a gate 57 to the input Tp rreip.

Thus, the scratch pulses are passed to the counters only during the time period, the resistor 40 of the Condensator 41 is given by the normal circuit.
