Pulse shaper control

Known conditioners control pulses f1,, 2) In one famous shapers IE bit thyristors shunted backwards through the diode auxiliary refill dros-, agricultural (1). The disadvantage of this formirovatelyanizkaya stability. Pulse shaper FIs can work on the principle of converting the light flux from the source LN (LED, incandescent and so on. N.) Special photodetector (photoelectric cell, photodiode), closed the narrow aperture in the current or voltage pulses that occur at the time of the passage of slots (short pulses Mu in Fig. To control the electronic devices are often used generator-shaper of single pulses, triggered either by pressing buttons or by powering (reset, installation, transfer to another mode, etc.). Such conditioners give only one impulse to external influence. The controller has a function of self-adjustment and flexible temperature control regulates the temperature of a smooth curve. The controllers can be installed surface-mounted or in the control cabinet. If the input file management logic-one level, then the output state of the first element (point B) will be determined by the voltage level at the point A. The voltage at point A is determined by the processes of charging and discharging the capacitor C through the resistor R. The AND gate DD1 performs under these conditions NOT function.

Pulse shaper control thyristor

For the formation of short pulses in games there are two methods: a derivation of the input pulses and pulse shaping using logs­cal circuits. Fig. Often in the control circuits necessary to use generators in which regardless of the position of the fronts of control signals provided undistorted (duration) forming the first and last pulses on the output. And the beginning of the first pulse should coincide with the beginning of the control signal. Synchronizer pulse contains channels 1. . . 3 phase voltage control, 4 channels. . . 6 by the line voltage control unit logic elements.

Generator of control pulses

For automation devices, remote control or checking of individual nodes of the circuit is sometimes required to transmit a packet of a certain number of pulse generators such simple scheme shown in Fig. 1.43. They last impulse packs can get shortened if the control signal has an arbitrary duration. Square wave generator square wave generator to generator chip under the scheme in Fig. The oscillator circuit diagram in Figure 2 makes it possible to separately adjust the pulse generator at three.
