Description

УСТРОЙСТВО дл  ВЬгаиТАНИЯ ЧАСТОТ ДВУХ DEVICE FOR DRIVING FREQUENCIES OF TWO

(54) НЕЗАВИСИМЫХ СИГНАЛОВ(54) INDEPENDENT SIGNALS

Изобретение относитс  к импульсной технике.The invention relates to a pulse technique.

Известно устройство дл  вычитани  частот, содержащее бистабильный элемент , который за счет использовани  логических вентилей совпадени  модулирует входную информацию упор доченно во времени. Запоминающа  бистабильна  схема в сочетании с другими вентил ми совпадени  определ ет, какой из вход,ных сигналов имеет большую частоту, а также разность частот этих сигналов l .A device for subtracting frequencies is known, which contains a bistable element that, by using a matching gate, modulates the input information in a time-ordered manner. The memory bistable circuit, in combination with other coincident gates, determines which of the input signals has a large frequency, as well as the difference of the frequencies of these signals l.

Недостаток схемы - использование принципа частотного компаратора, который даёт большую погрешность.The disadvantage of the scheme is the use of the principle of a frequency comparator, which gives a large error.

Наиболее близкое к предлагаемому изобретению устройство дл  вычитани  частот содержит два Зк-триггера, первый вход одного из соторых соединен с выходом первого трехвходового логического элемента И, первый вход i oторого соединен с шиной сигнала первой частоты, второй вход соединен с первым входом первого смесител , а третий вход подключен к выходу упом нутого tJK-триггвра и первому входу второго смесител , второй вход которого подключен к выходу второго ЗКтриггера и третьему входу второго The device for subtracting frequencies closest to the invention contains two 3k-triggers, the first input of one of which is connected to the output of the first three-input logic element I, the first input of iOther is connected to the signal bus of the first frequency, the second input is connected the third input is connected to the output of the mentioned tJK-trigger and the first input of the second mixer, the second input of which is connected to the output of the second ZKtrigger and the third input of the second

трехвходового логического элемента И, второй вход которого соединен со вторым входом первого смесител , третий ВХОДвторого трехвходового логического элемента И соединен с шиной сигнала второй частоты, а его выход подключен к первому входу второго ЗКтриггера , причем.вторые входы ЭКтриггеров соединены с шинами инверснь сигналов первой и второй частоты, а выходы смесителей через резисторы подключены к выходу устройства 2j.the three-input logic element And, the second input of which is connected to the second input of the first mixer, the third INPUT of the second three-input logic element And is connected to the signal bus of the second frequency, and its output is connected to the first input of the second ZKtrigger, and the second frequency, and the outputs of the mixers through the resistors are connected to the output of the device 2j.

Однако такое устройство не обладает достаточной помехоустойчивостью.However, such a device does not have sufficient noise immunity.

Цель изобретени  - повьаиение помехоустойчивости .The purpose of the invention is to improve noise immunity.
