Изобретение относитс к радиотехнике и может использоватьс в передатчиках радио- и многоканальной св зи.The invention relates to radio engineering and can be used in radio transmitters and multi-channel communication.
Известен частотный манипул тор, содержащий последовательно соединенные опорный генератор, импульснофазовый детектор и управл емый генег ратор, ко второму входу которого подключен выход элемента задержки, вход которого соединен с первым входом блока управлени , второй вход и первый выход которого соединены соответственно с выходом элемента задержки и с первым входом делител с переменным коэффициентом делени , выход которого подключен к третьему входу блока управлени fllA frequency manipulator is known that contains a series-connected reference oscillator, a pulse-phase detector and a controlled generator, the second input of which is connected to the output of the delay element, the input of which is connected to the first input of the control unit, the second input and the first output of which are connected respectively to the output of the delay element and with the first input a divider with a variable division factor, the output of which is connected to the third input of the control unit fll
Однако известный частотный мани пул тор имеет низкую помехозащищенность .However, the known frequency switch has a low noise immunity.
Цель изобретени - повышение помехозащищенности .The purpose of the invention is to improve the noise immunity.
Дл достижени этой цели в частотный манипул тор введены последовательно соединенные интегратор и управл емый блок задержки, выходTo achieve this goal, a sequentially connected integrator and a controlled delay unit, an output
J которого соединен со вторым входом импульсно-фазового детектора и четвертым входом блока управлени , второй и третий выходы которого подключены ко входам интегратора, приJ of which is connected to the second input of the pulse-phase detector and the fourth input of the control unit, the second and third outputs of which are connected to the inputs of the integrator, with
10 этом выход управл емого генератора соединен со вторым входом делител с переменным коэффициентом делени , выход которого подключен ко второму входу управл емого блока задержки,10 this output of the controlled generator is connected to the second input of a divider with a variable division factor, the output of which is connected to the second input of the controlled delay unit,
