Abstract

FIELD: radio engineering. SUBSTANCE: receiver has series-connected rejection filter incorporating chrominance-eliminating filter and two rejection filters, multiplier whose second input is connected through mixer to rejection filter output. Second input of mixer is connected to output of local oscillator. Multiplier output is connected to combined inputs of first, second, third, and fourth band filters whose outputs are used as device outputs and at the same time are connected to first, second, third, and fourth amplitude detectors, respectively, whose inputs are connected to adder inputs. Adder output is connected to threshold unit whose output functions as device output. EFFECT: improved noise immunity at narrow-band noise.

Изобретение относится к радиотехнике и может найти применение в устройствах контроля и анализа шумоподобных ФМн сигналов, служит для повышения помехоустойчивости при воздействии узкополосных помех. Предлагаемый приемник содержит последовательно соединенный фильтр, в состав которого входит обеляющий фильтр и два заградительных, перемножитель, второй вход которого через смеситель соединен с выходом заградительного фильтра. Второй вход смесителя соединен с выходом гетеродина. Выход перемножителя соединен с объединенными входами первого, второго, третьего и четвертого полосовых фильтров, выходы которых являются выходами устройства и в то же время соединены соответственно с первым, вторым, третьим, четвертым амплитудными детекторами, входы которых соединены с входами сумматора. Выход сумматора соединен с пороговым устройством, выход которого является выходом устройства.The invention relates to radio engineering and can be used in devices for monitoring and analysis of noise-like PSK signals, serves to increase noise immunity when exposed to narrow-band interference. The proposed receiver contains a series-connected filter, which includes a whitening filter and two barriers, a multiplier, the second input of which through a mixer is connected to the output of the barrage filter. The second input of the mixer is connected to the output of the local oscillator. The output of the multiplier is connected to the combined inputs of the first, second, third and fourth bandpass filters, the outputs of which are the outputs of the device and at the same time are connected respectively to the first, second, third, fourth amplitude detectors, the inputs of which are connected to the inputs of the adder. The output of the adder is connected to a threshold device, the output of which is the output of the device.
