Abstract

ФАЗОВЫЙ ДИСКРИМИНАТОР, содержащий два элемента И инвертор, причем вход инвертора и первый вход первого элемента И объединены и вл - ютс сигнальным входом фазового дискри ,минатора, выход инвертора соединен с первым входом второго элемента И, вторые входы первого и второго элементов И объединены и вл ютс опорным входом фазового, дискриминатора, отличающейс тем, что, с целью повьшени помехоустойчивости, в него введены два одновибратора, первый из которых включен между выходом первого элемента И и третьим входом второго элемента И, второй одновибратор - между выходом второго элемента И и третьим входом первого элемента И, при этом выходы первого и второго одновибраторов вл ютс соответственно первым и вторым выходами фазового дискриминатора. (ЛA PHASE DISCRIMINATOR, containing two elements And an inverter, the inverter input and the first input of the first element And are combined and are the signal input of the phase discriminator, minator, the output of the inverter is connected to the first input of the second element And, the second inputs of the first and second elements the reference input of the phase discriminator, characterized in that, in order to increase the noise immunity, two one-oscillators are introduced into it, the first of which is connected between the output of the first element AND and the third input of the second element and a second monostable multivibrator - between the output of the second AND gate and a third input of the first AND gate, the outputs of the first and second monostable multivibrators are respectively first and second outputs of the phase discriminator.

Claims

A PHASE DISCRIMINATOR containing two AND elements, an inverter, the inverter input and the first input of the first AND element being combined and being the signal input of the phase discriminator, the inverter output connected to the first input of the second AND element, the second inputs of the first and second AND elements combined and are the reference input of the phase discriminator, characterized in that, in order to increase the noise immunity, two single-vibrators are introduced into it, the first of which is connected between the output of the first element And the third input of the second element And, the second second monostable multivibrator - between the output of the second AND gate and a third input of the first AND element ^1, the outputs of the first and second monostable multivibrators are respectively first and second rows § The yields of the phase discriminator.
