Description

Image Brenting refers to the implication of those ksse. It is known a timing device for a sawtooth generator, containing a relaxation generator, an integrating capacitor, and a two-base diode tl. This device does not have the required stability. The closest to the pre-technological connection is the time setting device, which contains a static trigger whose output through a diode is connected to the input of a constant current source by one plate of an integrating capacitor, the other facing of which is connected via resistors to the geyrator with a common busbar and directly. gate of the output source h) repeater, the source of which is connected to the primary winding of the pulse transformer ijal Such a device does not have iobcho “chemical term stable and does not provide dsx: long prolonged time exposures The proposed timing device for a sawtooth generator in order to increase its thermal stability and increase the duration of time intervals introduced two additional exhaustive repeaters, the closures of which were combined with the first time, and the timeframe of the questionnaire asked them. connected to the primary winding of the pulsator gransforor, and the source of the second connection through a resistor with a drain of the output source followers. The drawing shows the principal cjs & ma described vremivvdyushvgo zgstroystvv, ja., Ustroyzstyo contains (gatvchesky rpitrTep 1, the pulse generator 2, the source of the repeaters 3, 4, the integrating capacitor 5, control source 6 worthy | 18, the output source is in a torus 19. The output signals are input from outputs 20, 21. Sources pi1 "nk in the scheme and posozava The device works as follows}" "In some time the transistor in njwDOM is connected to the circuit of a static trigger 1 arm , spvdooatvlio, the water supply T is closed and integrat The condenser 5 is charged by a controlled current source 8. While the charge of the injected capacitor 5 is small, the pulses from the generator 2 are amplified by the source followers 3, 4 and the current in the primary winding of the pulse transformer 18 is absent. the capacitor 5, the current repeater 3 is more and more locked) which will cause the current occurring due to the pulses from the pulse generator 2 and flowing through the open source follower 4 and the primary winding of the pulse Transformer 18 The emergence of impulses in the primary winding of a pulse transformer 18 will cause the impulse to receive its secondary winding, which from the output 20 arrive at the static trigger p 1 when the amplitude reaches the required level, its tilting will start - the left (according to the diagram) generator shoulder will start working two sawtooth strands, which is identical to that considered. After the static trigger I rolls over, the integrating capacitor 5 is discharged through the semiconductor light 7, ot closed right T1X1 H resistor static trz gera 1 and resistor 15 In such a scheme, there is nothing so far, "close to the bottom." A new tipping of the static trigger 1 will occur, leading to the beginning of the ap aa of the integrating capacitor 5. Then, the described processes are repeated. Izobrebek Vrvm formula is a driver for a sawtooth generator, which contains a static trigger, the output of which is connected via a diode to the output controlled by the SINTER constant source and the first plate of the integrating capacitor, the second plate of which is connected through resistors to the output of the pulse generator and the busbar and directly the gate of the output source follower, the source of which is connected to the pers & unwinding of the pulse-type transformer, is distinguished by the fact that, on the increase point, the thermostat ab lnostv and increase the duration of time intervals, two additional sink repeaters are introduced into it, the gates of which are connected to the first plate of the capacitor, the source of one short circuit is connected to the first winding of the pulsed tracer and the second terminal through the resistor is connected to the drain of the second pulse repeater.
