Изобретение огносигс к радиотехнике , а именно к системам передачи информации .The invention of ognosigs to radio engineering, namely to information transmission systems.
Известно устройство дл приема цифровой информации, содержащее регенератор , выход которого соединен с первым входом фазового дискриминатора и одним входом регистра, выход которого соединен со вторым входом фазового дискриминатора 11.:A device for receiving digital information is known, which contains a regenerator, the output of which is connected to the first input of the phase discriminator and one input of the register, the output of which is connected to the second input of the phase discriminator 11 .:
Однако известное устройство дл приема цифровой информации обладает низкой помехоустойчивостью.However, the known device for receiving digital information has low noise immunity.
Цель изобретени - повышение помехоустойчивости .The purpose of the invention is to improve noise immunity.
Указанна цель достигаетс тем, что в устройство дл приема цифровой информации , содержащее регенератор, выход которого соединен с первым вкоаоц фазового дискрим 1натора и одним входом регистра , выход которого соединен со вторым входом фазового дискриминатора, введен умножитель частоты, выход кото- рого соединен с первым входом регенератора и с другими входами регистра, прччем второй вход регенератора соединен со входом умножител частоты.This goal is achieved in that a device for receiving digital information, containing a regenerator, the output of which is connected to the first coaxial phase discriminator and one input of the register, the output of which is connected to the second input of the phase discriminator, is entered into the frequency multiplier, the output of which is connected to the first the input of the regenerator and other inputs of the register, where the second input of the regenerator is connected to the input of the frequency multiplier.
На чертеже приведена структурна электрическа схема предлагаемого устройства .The drawing shows a structural electrical circuit of the proposed device.
Устройство дл приема цифровой тшформашга содержит регенератор I, умножитель 2 частоты, регистр 3 к фазовый дискриминатор 4.The device for receiving digital data format contains a regenerator I, a frequency multiplier 2, a register 3 to the phase discriminator 4.

Устройство работает следующим образом .The device works as follows.
Демодулируемый сигнал подаетс на, умножитель 2 частоты, коэффициент ум- ножени которого (J выбираетс исход нз The demodulated signal is fed to, a multiplier of 2 frequencies, the multiplication factor of which (J is chosen as the outcome from
15 необходимого щага квантовани и обеспечени подавлени манипул ции фазы. По- лученные на его выходе импульсы частот )f (efj - номинальное сигнала,Д - ее отклонение) 15 necessary quantization steps and provide suppression of the phase manipulation. Pulses of frequencies received at its output) f (efj is the nominal signal, D is its deviation)
