Изобретение относитс к вычислительной технике и может быть использовано, например, в системах ввода-вывода и телеобработки информации с использованием фильтров Уолша.The invention relates to computing and can be used, for example, in input / output systems and teleprocessing of information using Walsh filters.

Известно устройство дл ввода телеметрической информации, содержащее пороговой элемент и каналы св зи, каждый из которых состоит из триггера, соединенного с выходным вентилем и элементом запретаA device for inputting telemetry information is known, which contains a threshold element and communication channels, each of which consists of a trigger connected to an output valve and a prohibition element.

Устройство выбирает из множества входных сигналов наибольшие и пропускает их на выходные шины; наличие линейных схем, снижающих общую надежность известного устройства.The device selects the largest from the set of input signals and passes them to the output bus; the presence of linear circuits that reduce the overall reliability of the known device.

Целью изобретени $юл етс повышение работы устройства.The aim of the invention is to improve the operation of the device.

Дл этого прюдлагаемое устройство содержит в каждом канале регистр сдвига, элемент и элемент задержки и инвертор, причем выход регистра сдвига подключен к одному из входов выходного вентил и одному из входов элементаи второй вход которого подключен через элемент задержки к нулевому выходу триггера и к одному For this, the proposed device contains in each channel a shift register, an element and a delay element and an inverter, with the output of the shift register connected to one of the inputs of the output valve and one of the inputs of the element and whose second input is connected through a delay element to the zero output of the trigger and to one

из входов элемента запрета, выход которого через инвертор подключен к третьему входу элемента и, а его выход соединен с единичным входом триггера и с одним из входов порогового элемента.from the inputs of the prohibition element, the output of which through the inverter is connected to the third input of the element and, and its output is connected to a single trigger input and to one of the inputs of the threshold element.

Предлагаемое устройство представлено на чертеже, где 1 - входные шины; 2 - регистр сдвига, 3 - элемент И 4 - триггер , 5 - выходной вентиль, 6 - выходные шины, 7 - элемент задержки, 8 - пороговый элемент, 9 - элемент запрета, 10 инвертор .The proposed device is shown in the drawing, where 1 is the input bus; 2 - shift register, 3 - element AND 4 - trigger, 5 - output valve, 6 - output bus, 7 - delay element, 8 - threshold element, 9 - prohibition element, 10 inverter.

Входные сигналы в виде tl -разр дных кодов по шинам 1 подаютс в регистры сдвига 2, старшими разр$щами вперед. Работа протекает за П тактов.The input signals in the form of tl-digit codes for bus 1 are fed to shift registers 2 by higher bits ahead. The work takes place at the P clock.

Пусть в первом такте с выхода регистра 2 4 сдвига снимаетс единичный сигнал При этом элемент И 3 t открываетс и триггер 4 i устанавливаетс в единичное состо$шие. Сигнал с выхода регистра 21 через выходной вентиль 5 1. поступает на выходную шину 6 iLet a single signal be taken off in the first clock cycle from the output of the 4 4 shift register. At the same time, the AND 3 t element is opened and the trigger 4 i is set to unity. The signal from the output of the register 21 through the output valve 5 1. enters the output bus 6 i

Claims

The zero signal from the zero output of the trigger 4 1 through the delay element 7 t is fed to the input of the element and I, thereby forming the falling edge of the output signal of the element and 3 1, which also goes to the corresponding input of the threshold element 8. If the output of the register 2 A is removed signal, then trigger 4 remains in state O. The threshold element in each clock cycle adds signals from the corresponding shift registers. The trigger 4 t, if it has triggered, saves a single state all the time of operation, the element 3– i passes only one signal to the threshold element 8, and the output valve 5 i will be open all the time. At the moment when the number of signals at the input of the threshold element 8 exceeds a certain threshold, the output signal of the threshold element 8 from the banning elements of the prohibition 9 in the channels, the trigger of which by this time saved the state O. On the outputs of the corresponding inverters 1O there will be zeros passing single signals through AND 3 elements to the inputs of the corresponding flip-flops 4. Thus, for ft cycles on the output tires 6, the codes of the largest signals, the number of which is determined by the setting of the threshold element 8. After the fi-th cycle At 11, a reset signal is received, which returns the triggers 4 to the initial state. Apparatus for inputting telemetry information, comprising a threshold element and communication channels, each of which consists of a trigger connected to an output valve and an inhibit element, characterized in that, in order to increase the reliability of the device, it contains in each channel a shift register , And element, delay element and inverter, and the shift register output is connected to one of the inputs of the output valve and to one of the element inputs and the second input of which is connected through the delay element to the zero output trigger and to one of the inputs zlementy prohibition, the output of which is connected through an inverter to the third input of the AND gate and its output connected to the input of flip-flop unit and one of the inputs of the threshold element.
