The invention relates to a pulse technique and can be used in information and measurement systems and control systems for the selection of pulses in duration. five

The aim of the invention is to eliminate the need to set additional triggers in the initial state.

The drawing shows the structure on the scheme of the proposed pulse selector.

Pulse selector, contained 1 pulse generator, the output of which is connected to the counting input of the pulse counter 2, the installation inputs connected to the outputs of the form-ipath 3 pulses and the inputs of the first trigger 4, the first and second elements of AND 5 and 6, the first inputs of which are connected These are connected to the output of the pulse counter, and the second to the outputs of the first trigger 4, respectively, and the outputs are connected to the inputs of the second trigger 7, while the input of the pulse former 3 is connected to the input bus 8, and the output of the second trigger 7 is connected to the output bus 9.

The pulse selector works as follows.

In the initial state, the triggers 4 and 7 are set to the zero position.

This is the duration of the “impulse interference. The pulse of the overflow of the counter 2 pulses passes through an open signal from a single output of the trigger 4 element 5 to the input of the trigger 7 and rolls it over, and a selective pulse begins to form on the bus 9 of the device.

The fall of the pulse on the input bus 8 triggers the pulse shaper 3, at the second output of which a pulse is formed along the decay of the selectable one. This pulse returns the trigger 4 to the initial state, then a single signal appears on its inverse output, opening element AND 6. At the same time, the pulse from the second output of the driver 3 pulses resets the counter 2 pulses and it starts counting the number of pulses from the generator 1 clock pulses . An overflow pulse from the output of the counter 2 pulses passes through the open element 6 and sets the trigger to its initial state, while the formation of the pulse on the output bus 9 of the device stops.

Invention Formula The pulse selector, which contains a clock pulse generator, an input bus connected to the input of the pulses, receives pulses from l-35 world power pulses, the outputs of which are an example when the power is supplied (not shown). On the counting input of the counter 2 RATOR 1 clock pulses. The overflow signal of the counter 2 pulses through the AND 6 element confirms the initial state of the trigger 7. A selectable pulse arriving at the bus 8 starts the shaper of 3 pulses, which at the first output generates a pulse at the front of the selectable one. This pulse triggers trigger 4 into one state and resets the counter 2 pulses to the initial state. The counter 2 pulses begins to count the number of pulses coming from the output of the generator 1 clock pulse-SOB. The capacitance of counter 2 is selected from the condition that no impulse noise selector is output, the duration of which is significantly less than the duration of information pulses, i.e. it is defined as much as possible admitted.
