Abstract

FIELD: radio engineering. SUBSTANCE: device has three subtraction units 1, 6, 9, which inputs are joined and are connected to device input. Output of first subtraction unit 1 is connected to second input of second subtraction unit 6 through serial circuit which consists of multiplier 2, band-pass filter 3, phase shifter 4 and multiplier 5. Output of subtraction unit 6 is connected to input of first controlled-gain amplifier 7 which output is connected to second input of subtraction unit 1 and to second input of third subtraction unit 9 through serial circuit which has clipper 12, synchronous phase filter 8, and second controlled-gain amplifier 10. Output of subtraction unit 9 serves as device output. Second input of synchronous phase filter 8 is connected to input of device. Reference signal is received by multipliers 2 and 5 from signal copy generator 11. EFFECT: increased functional capabilities.

Изобретение относится к области радиосвязи и может найти применение в системах связи с широкополосными сигналами. Устройство содержит три вычитателя 1,6,9, входы которых объединены со входом устройства. Выход первого вычитателя 1 через последовательно соединенные перемножитель 2, полосовой фильтр 3, фазовращатель 4, перемножитель 5 соединен со вторым входом второго вычитателя 6. Выход вычитателя 6 соединен со входом первого блока с регулируемым коэффициентом передачи 7, выход которого соединен со вторым входом вычитателя 1 и через последовательно соединенные ограничитель 12, синхронно-фазовый фильтр 8, второй вход которого соединен со входом устройства, и второй блок с регулируемым коэффициентом передачи 10 соединен со вторым входом третьего вычитателя 9. Выход вычитателя 9 является выходом устройства. Опорный сигнал на перемножители 2 и 5 поступает с генератора копии сигнала 11.The invention relates to the field of radio communications and may find application in communication systems with broadband signals. The device contains three subtractors 1,6,9, the inputs of which are combined with the input of the device. The output of the first subtractor 1 through a series-connected multiplier 2, a bandpass filter 3, a phase shifter 4, a multiplier 5 is connected to the second input of the second subtractor 6. The output of the subtractor 6 is connected to the input of the first block with an adjustable transmission coefficient 7, the output of which is connected to the second input of the subtractor 1 and through a series-connected limiter 12, a synchronous-phase filter 8, the second input of which is connected to the input of the device, and the second block with an adjustable gear ratio 10 is connected to the second input of the third a subtractor 9. The output of subtractor 9 is an output device. The reference signal to the multipliers 2 and 5 comes from the generator of the copy signal 11.
