DIGITAL DETECTOR OF PERIODIC PULSED SIGNALS BURSTS Russian patent published in 2016 - IPC H03K27/00 

FIELD: electronics.

SUBSTANCE: invention relates to digital processing of pulsed signals and can be used in devices for primary processing of location and navigation equipment. Device contains a counter connected to a decoder and the first AND element, inputs of which are connected to outputs of a video signals normalizer and a delay line, the first OR element and series-connected the second OR element, a shift register, the second AND element and a NOT AND element, herewith the first and the second inputs of the first OR element are connected to the output of the video signals normalizer and the shift register output, and the output of the first OR element is connected to the delay line input, the output of which is connected to the second input of the second AND element, the output of which is connected to the input of the counter, the reset input of which is connected to the output of the first AND element and is connected to the first input of the second OR element, the second input of which is connected to the output of the NOT AND element, the inverting input of which is connected to the output of the decoder.

EFFECT: technical result is the increase of noise-immunity of the detector by feedforward comparison through all n signals of the burst.
