Abstract

The invention relates to measuring and computing equipment, radio engineering and can be used in information conversion and processing devices. The purpose of the invention is to reduce the complexity of the technical implementation and enhance the functionality by delaying pulses arriving at a random point in time, and increasing accuracy by ensuring independence of the delay from the clock frequency and the delay time. For this purpose, the front driver 1, the generators 3 and 4 pulses of the delay time, and the elements BAN 5 and 7 are added to the device containing the driver 2 and the element 8 or 8. The device allows delaying the pulses arriving at any arbitrary point in time. At the same time, the accuracy of the final result is determined by the stability of the delay-time pulse generator. 4 il. g (L

The invention relates to measurement, computational, and radio engineering and can be used in data conversion and processing devices.

The aim of the invention is to reduce the complexity of the technical implementation and enhance the functionality by delaying pulses arriving at a random point in time, and improving accuracy by ensuring independence of the delay from the clock frequency and the delay time.

Fig. 1 is a block diagram of a device for delaying rectangular pulses; 2, 3 and-4 are timing diagrams explaining his work, -

The device contains a front-side driver 1, a recession driver 2, two generators 3 and 4 of the delay time pulse, the elements of the prohibition 5-7 and the element OR 8,,

The inputs of the front formers 1 and decay 2 are connected to the input of the device, the output of the front former 1 is connected to the generator 3 input of the delay time pulse, and the output of the double down generator to the generator 4 entrance of the delay time 3, the generator 3 output is connected to the forward input of the first BREAD element 5 and to the inverse input of the BANNER element 6, the other inputs of which are connected to the input of the device, the output of the prohibition element 5 is connected to the inverse input of the BAN 7, the direct input of which is connected to the output of the generator 4, and the output to the input or 8, another input is connected to the output of BAN 6, and the output is the output of the device.

Front Shaper 1 is used for

bypassing the input pulse, and in the general case can vary by changing the control action

generator control inputs, pos. blunt to the control input of the device. But at the same time the duration of the pulses generated by both generators are equal to each other (FIG.

2.3, 2.4).

The device operation is as follows.

If necessary, delay the pulse for a time shorter than its duration (Fig. 2), a pulse arrives at the device input, which must be delayed for a duration of €. In this case, the front 1 former is formed by its front (Fig. 2.1), and

The decay sensor 2 is its decline (Fig. 2.2). At the same time, the generator 3 generates a pulse with a duration t (Fig. 2.3). The same pulse with diversity in time is generated by generator 4

(Fig. 2.4). On the BAN 6 element, the initial impulse is shortened by time (Fig. 2.6), and on the OR 8 element, a pulse of € duration (Fig. 2.8) is added to its decay,

coming through the element BAN 7 (Fig. 2.7).

At the output of the element OR 8, an impulse appears which is delayed relative to the input for a time s.

If it is necessary to delay the pulse for a time longer than its duration (Fig. 3) J, the front (Fig. 3.1) and the decay (Fig. 3.2) stand out from the incoming pulse. In this case, the generators 3 (Fig. 3.3) and 4 (Fig. 3.4) are started. The impulse at the output of the prohibition element 5 is equal in duration to the pulse of the generator 3 with the duration of the input impulse (Fig. 3.5). Time

selection of the front of the incoming pulse. 45 pulses from the generator output

Sa, in the case of its allocation, starts generator 3 (Fig. 2.1, 3.1, 4.1).

The decay shaper 2 serves to decay the incoming pulse and form the start-up pulse of the generator 4 (Fig. 2.2, 3.2, 4.2).

Generators 3 and 4 pulse delay times are completely identical. They are triggered by pulses from the outputs of blocks 1 and 2, respectively, and form single rectangular pulses of highly stable duration. The duration of these pulses f is equal to the value of the delay time for which non-4 and the BAN 5 element is an incoming pulse delayed by time 1 (Fig. 3.7). Through the element OR 8 it enters the output of the device (Fig. 3.8).

If necessary, delay

impulse for a time equal to its duration, the operation of the device in this case is clearly represented in the time diagrams (figure 4).

The proposed device allows the delay of pulses arriving at any arbitrary point in time.
