Изобретение относитс ;к устройствам обработки информации, обнаружени и измерени нараметров сигна-тов.The invention relates to devices for information processing, signal detection and measurement.

Известны оптоэлектронные устройства обработки оптических сигналов с оптическ мвтранспорактами , реализуЬишми раапоже ние по функци м Уолша, оптоэлектронные анализаторы спектра Адамара, оптоэлектронвые классификаторы и т. д. lij. Optoelectronic devices for processing optical signals with optical transport structures, realizing Walsh functions, Hadamard optoelectronic analyzers, optoelectronic classifiers, etc. are well known.

Известен также оптоэпектронный анагшзатор сигналов, срдержащюс фототфиёмное yciv. ройство, выход которого соединен с первым входом сумматора, второй вход сумматора подключен к выходу синхронизатора, при этом второй выход синхронизатора соединен С генератором базисных функций, а также устройство прин ти решений 2 J,Also known is the optoelectronic signal suppressor, which suppresses the photo-effect yciv. The device whose output is connected to the first input of the adder, the second input of the adder is connected to the output of the synchronizer, while the second output of the synchronizer is connected to the generator of basic functions, as well as the decision maker 2 J,

Однако такие анализаторы не обеспечивают возможности обработки случайного сиг,нала в реальном масштабе времени.However, such analyzers do not provide the possibility of processing a random signal in real time.

Цель изобретени - обеспечить обработ ку случайных.сигналов в реальном масштагбе времени.The purpose of the invention is to provide processing of random signals in real time.

Это достигаетс тем, что в оптоэлектронный анализатор сигналов, содержащий фото2This is achieved by the fact that in an optoelectronic signal analyzer containing photo2

Claims

The sync pulse from snachometer 7 triggers a generator 6, which generates pulses corresponding to all the orders of the basis functions to start the decomposition interval T (see FIG. 2) simultaneously transmitted by the shift register 5 to the unit 1, the signal being examined as changes in the intensity of the light flux are applied to all elements of the device 1 at the same time, where the amplitude of the signal under study is multiplied by the corresponding values of the decomposition functions (1, 1 or 0 for the Walsh functions, for example The signals arrive at the adder 2 elements, where the coefficients of the decomposition of the follow signal are formed, which are compared each time to the reference coefficients in block 3. At the moment when the coefficients of decomposition into adder 2 and reference ones coincide, this happens at the moment corresponding to the end of the decomposition interval A channel in which the beginning of the signal coincides with the beginning of the decomposition interval) in device 4 receives a coincidence signal carrying information about the arrival at the input of the device. The value of the signal is the same as the reference, about the time of its end (with an accuracy of Db of the period of operation of the device). An optoelectronic signal analyzer containing a photodetector, the output of which is connected to the first, an input of the adder, a second input of the adder is connected to the output of the synchronizer, while the second output of the synchronizer is connected to a generator of basic functions, as well as a decision-making device 4fTO | in order to process random signals in real time, a shift register and a comparison block are entered into it, the input of the comparison block is connected to the output of the adder, and the output is connected to the first input of the decision unit | the second input is connected to the third sync nizer output, the input of the shift register is connected to the output of the basic function generator, and the shift of the shift register is connected to the input of the photoreceiver.
