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

Known selectors pulses, based on their timing and amplitude (see, for example, U.S. patent No. 3922676, author's certificate No. 894851, 1239852, 1396268, 1624676, patents No. 2173935, 2168854, 2235418 and others), as well as the selectors described in the 2nd and 3rd chapters of the book Antimachia, Vcctc "Selectors pulses". - M.: Owls. radio, 1966

Known selectors closest to the present invention is a selector pulse sequence in patent No. 2235418, M CL 7 NC 5/19 priority from 26.11.2002, which is selected as a prototype.

This selector allows discriminates regular and random pulse sequence amplitude and pulse duration.

The disadvantage of this selector is that it is not possible to separate periodic pulses with specified parameters in the duration and amplitude of pulses with the same parameters on the duration and amplitude, but appear at random points in time.

The objective of the invention is the creation of a selector pulse sequence with more functionality, allowing you to share otsilindrovannye periodic pulse is s with a given amplitude and duration of pulses with the same parameters on the duration and amplitude, 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 with the first output selector, the second output of the input driver, which generates pulses at the moments corresponding to the rear edge of the input pulses, connected to the first input of the adder, the output of which is connected to series-connected multi-level 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 key, and the first delay unit, added new elements and relationships, namely the sawtooth generator, the input of which is connected to the input bus and an output connected to the second input of the adder, the output switch is connected to the input of the second unit delay element And the first input of which is directly, and the second through the first delay unit connected to the first output of the selector, the output element And the second output selector, and subtractive device, the first and second inputs which are connected respectively with the first and second outputs of the CE is the sector, and the output of subtractive device is the third output of the selector.

A structural scheme selector is presented in figure 1, and timing diagrams explaining the principle of its operation is shown in figure 2.

The selector pulse sequence contains the input shaper pulses 1, an input connected to the input bus, to the input of the sawtooth generator 4 and the third input 2 delay unit, the output of which through the key 3 is connected to the first output of the selector. The second output of the input driver 1 is connected to the first input of the adder 5 to the second input of which is connected to the output of the sawtooth generator 4. The output of the adder 5 via a serially connected multi-level 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, the input connected to the output of the switch 8, and the output of the trigger 9 is connected with the control input of the key 3. The first input element And 10 directly, and the second input through the first delay unit 11 is connected to the first output of the selector, and the output element And 10 connected to the second output of the selector. The first and second inputs of subtractive device 12 are connected respectively with the first and second outputs of the selector, and the output of subtractive device connected to the third you the ode selector.

The proposed selector works as follows. Input pulse sequence (figa), which along with other pulses are both periodic and random pulses with specified parameters in the duration and amplitude (in the drawing they are colored different shades), is applied to the input shaper 1, to the input of the sawtooth generator 4 and to the input of the third 2 unit delays. The cutting edge of the input pulse is triggered sawtooth generator 4, and the rear front of the input pulses break fluctuations of the generator. Thus, at the output of the sawtooth generator 4 pulses of sawtooth waveform, the amplitude of which is proportional to the duration of the input pulses (figb). These pulses to the second input of the adder 5, and the first input of the adder pulses from the second output of the input shaper 1 corresponding to the rear edge of the input pulse and is equal to the amplitude of the input pulses (pigv). At the output of the adder 5 appears pulses (high), 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 distributed by its level is m (figd). 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<Umaxcharacterizing this level (channel). The switch 8 can be connected to the first input of the trigger 9 any channel multilevel amplitude selector 7. When power is applied, for example, at the k-level multi-level amplitude selector 7 these pulses arrive at the switch 8 (fige) and its output serves at the first input of the trigger 9, setting 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 switch 8 during a given pulse duration tand(Figi). At the output of the trigger 9 appears pulses (figs)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(Figi). The output of the key 3, i.e. to the first output of the selector will pass only pulses with predetermined duration tand and amplitude Uand(FIGC). Among these pulses are both periodic pulses, and the pulses appearing at random points in time. With the exit key 3 pulses directly served at the first input element and 10, And to the second input of this element pulses delayed in the first delay unit 11 at the time, equal to the repetition period Tandpulses (Figl). The output of the element 10, which is the second output of the selector will only periodic pulses (film). The first and second inputs of subtractive device 12 receives pulses respectively with the first and second output selector, and the output of subtractive device, which is the third output of the selector will pass the pulses with a given amplitude and duration, but appear at random points in time (fign).

Thus, the use of the proposed new selector elements and relationships allows to extend the functionality of the selector for selecting pulses with the specified parameters and to allocate periodic pulses with specified parameters in the duration and amplitude at one output and the other output select pulses with the same parameters on the duration and amplitude, but appear at random points in time.

The selector pulse sequence containing the input formirovanie the b 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 with the first output selector, the output of the input shaper pulses, which pulses of constant duration proportional to the amplitude of the input pulses at the moments corresponding to the rear edge of the input pulses, connected to the first input of the adder, the output of which is connected to the input multi-level amplitude selector whose outputs are connected to inputs of the switch, the output switch connected to the S-input of the trigger, R is the input connected to the output of the second delay unit, the trigger output is connected with the control input of the key, and the first the delay unit, characterized in that it additionally introduced the sawtooth generator, the input of which is connected to the input bus and an output connected to the second input of the adder, the output switch is connected to the input of the second unit delay element And the first input of which is directly, and the second input through the first delay unit connected to the first output selector, which is formed by a sequence of pulses with predetermined duration and amplitude, the output element And the second output selector, which are formed periodic pulses with a given duration and amplitude, and subtractive device, the first and second inputs which connected with respective first and second outputs of the selector, and the output of subtractive device is the third output of the selector, which pulses with a given duration and amplitude appearing at random points in time.
