Description

The invention relates to a pulse technique and can be used to reconstruct distorted pulses.

The purpose of the invention is to eliminate the edge distortion of signals following at different wiring speeds.

electrical circuit of the proposed device; in fig. 2 - stress esters, which remove his work.

A device for regenerating telegraph pulses contains a divider. 1, And 2, shaper 3 pulses, counter 4, decoder 5, shaper 6 reference pulses, consisting of trigger 7, decoder 8, And 9 element and counter 10.

The device works as follows.

In the initial state, the counter 4, as well as the counter 10 and the trigger 7 of the driver 6 are reset. Clock pulses are 25, i.e. in zero (fig. 2d). Wherein

These flows through divider 1, the division factor of which is selected depending on the speed of wiring and the volumes of counters 4 and 10 so that the filling time of these counters would be equal to the duration of the reference pulse, applying to the control inputs of divider 1 the binary code of the numerical value of the coefficient dividing by the second input of the element 2 and the clock input of the driver 6 reference impulses, pass further to the first input of the element 9 of the driver 6.

If, for example, a distorted pulse (but not more than 50%) arrives at the device input, say elongated (Fig. 2a), then on the front of this pulse a shaper of 3 pulses forms a short pulse (Fig. 26), which zeroed the counters 4 and 0, and during the effect of this distorted pulse on the first input of the element AND 2, the counter 4 counts the post. drinking at its input (fig. 2c) from the output of the element And 2-stroke pulses. As soon as counter 4 counts the number of pulses equal to half of its volume.

the Pi 9 closes and stops passing the heartbeats to its output. As a result, a single impulse is formed at the output of the imager - 6 reference pulses; its duration is equal to the reference pulse (Fig. 2e).

If a packet of pulses arrives at the input of the device, for example, consisting of two shortened pulses (Fig. 2a), the operation of the device will differ from that described by the fact that counter 4 will, after a time equal to the duration of one reference pulse, be reset and begin clock counting again, etc. As the number of counted pulses produces a pulse at its output (Fig. 2d),

catfish, issued by the decoder 8, arriving at the information input (for example, 0-input of the O-flip-flop) of the flip-flop 7 (Fig. 2d) and FIG. 2g), but the decoder 5, tuned to its number -gg as the setup input of the rigger 7 to one, outputs to its output the pulse state is asynchronous (Fig. 2d), which goes to the information, then the trigger 7 will remain in the active input of the imaging unit 6, the reference state — a single state, regardless of these pulses.

The shaper 6 reference pulses works as follows.

The impulse arriving at the information input of the imaging unit 6 enters the installation (one) input of the trigger 7 and translates the latter into a single state (Fig. 2e), which means the beginning of the formation of the reference

the same potential opens the element And 9, the first input of which receives the clock. pulses. Counter 0 begins to count clock pulses from the output of the element And 9 (Fig. 2e). As soon as counter 10 counts the number of pulses, equal to the value of its volume (corresponding to a time equal to the duration

 reference pulse), a decoder. 8 will issue a single impulse (Fig. 2g), which will go to the information input of trigger 7, to transfer it to the opposite state g

five

the Pi 9 closes and stops passing the heartbeats to its output. As a result, a single impulse is formed at the output of the imager - 6 standard impulses; its duration is equal to the reference impulse (Fig. 2e).

If a packet of pulses arrives at the input of the device, for example, consisting of two shortened pulses (Fig. 2a), the operation of the device will differ from that described in that the counter 4 will, after a time equal to the duration of one reference pulse, begin to zero and clock counting again, etc. As the number of counted pulses produces a pulse at its output (Fig. 2d),

45 which will run the shaper 6 reference impulses. Moreover, the impulse arriving 1 to the information input of the imaging unit 6 (trigger input 7) from the output of the decoder 5 will coincide in terms of impulse 50

catfish, issued by the decoder 8, according to its information input. Thus, at the output of the trigger 7 (and hence at the output of the device) a pulse is generated, the duration of which will correspond to the duration of two reference pulses.

The device works similarly if a distorted packet of three (Fig. 2a on the right) or more distorted pulses arrives at the input. In this case, the output of the device will form a pulse with a duration that is a multiple of the reference one, three or more times (depending on how many pulses entered the device input).

By changing the division factor of divider 1, we can eliminate the edge distortions of sequences of impulses that follow at different speeds.
