The proposed selector refers to the pulse technique and can be used in devices analysis for extracting pulses with specified parameters in duration and amplitude.

Known selectors pulses, based on their timing and amplitude (see, for example, U.S. patent No. 3922676, inventors ' certificatesâ„–â„–894851, 1239852, 1396268, 1624676, patents No. 2173935, 2168854 and others), as well as the selectors described in the 2nd and 3rd chapters of the book of O. I. Timakova, C. K. Lyubchenko "Selectors pulses", ed. The owls. Radio, Moscow, 1966,

Known selectors closest to the proposed selector is in patent No. 2173935, M CL 7 H 03 To 5/19 priority from 18.04.2000, that is the sequences by three parameters, namely amplitude, pulse duration and repetition period.

A disadvantage of this device is that it does not allow discriminates pulses with specified parameters in the duration and amplitude appearing at random points in time.

The objective of the invention is the creation of a selector pulse sequence which discriminates as periodic pulses with a given amplitude and duration, and appearing at random points in time.

The problem is solved in that the selector pulse sequence containing the input shaper pulses, an input connected to the input bus and to the input of the third delay unit, the output of which through the key connected to the output bus, the first output of the input shaper is connected to the input of the first delay unit and connected in series adder, multilevel amplitude selector and switch, the output of which is connected to the first input of the trigger, a second input connected to the output of the second delay unit, and the trigger output is connected with the control input of the key of the new relation, namely the second output of the input shaper, at which pulses in m shaper, connected to the first input of the adder, a second input connected to the output and second input of the third delay blocks.

A structural scheme of the selector shown in Fig.1, a timing diagram explaining the principle of its operation is shown in Fig.2.

The selector pulse sequence contains the input shaper pulses 1, an input connected to the input bus and to the input of the third 2 delay unit, the output of which through the key 3 is connected to the output bus selector. The first output driver 1 is connected to the first input 4 of the delay unit, the output of which is connected to the second input of the adder 5 and the second input 6 of the delay block. The second output of the input driver 1 is connected to the first input of the adder 4, the output of which is connected in series through a multilevel amplitude selector 7 and the switch 8 is connected to the first input of the trigger 9 to the second input of which is connected to the second output 6 of the delay unit, and the output of the trigger 9 is connected with the control input of the key 3.

The proposed selector works as follows. Input pulse sequence (Fig.2A), which along with other pulses are both periodic and random pulse the I input the imaging unit 1 and the third input 2 delay block. The first output of the input shaper 1 pulses of constant duration proportional to the amplitude of the input pulses and their corresponding leading edge (Fig.2B) and the second output - similar pulses corresponding to the rear edge of the input pulse (Fig.2B), which are served at the first input of the adder 5. The pulses from the first output of the input shaper 1 is delayed in the first 4 block delay time equal to the specified duration of tand(Fig.2G), and fed to a second input of the adder 5, and the second input 6 of the delay block. At the output of the adder 5 appears pulses (Fig.2D), which provide information about the amplitudes and durations of the input sequence. From the output of the adder 5 pulses at multi-level amplitude selector 7, where depending on the total amplitude of the input pulses are divided by level (Fig.2E). Each channel of the multi-level amplitude selector 7 transmits on its output pulse only when the amplitude of the total voltage U lies in some interval Umin<U maxcharacterizing this level (channel). The switch 8 can be connected to the first input of the trigger 9 any channel tiered am the selector 7 these pulses arrive at the switch 8 (Fig.2ZH) and its output serves at the first input of the trigger 9, front front placing it in one state. In the zero state, the trigger 9 is set by the pulses from the output of the second 6 unit delay delayed relative to the pulses at the output of the first 4 units of the delay time specified pulse duration tand(Fig.2H). At the output of the trigger 9 appears pulses (Fig.2i), corresponding to the pulses of a given duration tandand amplitude Uanddelayed relative to the input sequence at time tand. The pulses from the output of the trigger 9 is received on the control input of the key 3, the other input of which is fed an input sequence of pulses, delayed by a time equal to the specified duration tand(Fig.2K). The exit key 3 will pass only pulses with predetermined duration tandand amplitude Uand(Fig.2l). Among these pulses are both periodic pulses, and the pulses appearing at random points in time. If you set a different time delay blocks delay and switch to connect to another channel multilevel amplitude selector, you can select pulses with a different set duration and amplitude.

Thus, the use of the proposed new selector links and choosing the different options on the duration and amplitude.
