Pulse shaper

In the construction of generators, timers and other similar devices generally used RC-Timing chain, whose work is based on the charge and discharge of the capacitor through a resistor from the dc source. These RC-circuit is connected, as a rule, the various active devices - transistors, op amps, comparators. The device, a circuit diagram is shown in Fig. 1 forms any desired number of pulses in the range from 1 to 10. It can be used in apparatus control operation of the digital nodes, encoder codes or commands, switches, and so on. N. From the known devices of this purpose shaper is simple construction, a small number of integrated circuits, as well as small (less than 4.5 mW) power consumption, it can be used in devices with independent power supply. The generator is connected to the separation (buffer) amplifier. A small capacitor can be used to adjust a specific quartz crystal at exactly vyde­fief frequency. In the development of digital devices often required to generate pulses that are linked to the input signal. If you do not meet high requirements for stability and duration of the pulse can be applied on the basis of the differentiating circuit (Fig. To generate pulses having the required parameters and ensure that the potential isolation of power and control circuits Apply­conditioners are built on the basis of opto-electronic or transformer­regulatory elements.

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. Material Application registers a pulse shaper .Registry shift are connected in series triggers a chain.

Shift registers are connected in series triggers a chain. The basic mode of operation - a shift bits of code written in these triggers, that is, the clock signal contents of each of the previous flip-flop corresponds to the next in order to trigger the chain.
