Description
1 Изобретение огносигс к импульснойгезшикё и может быть использовано при обработке частотно-мопулированных сигналов.1 The invention of ognosigs to pulsed magnetic and can be used in the processing of frequency-controlled signals.
Известно устройство ц вычитани частот, содержащее ива блока прив зки импульсов входаых частот к двум последовательност м несовпадающих тактовых импульсов и реверсивный счетчик, причем импульсные входы сложени и вычитани реверсивного счетчика подключены к выходам блоком прив зки импульсов входных частот 13.A device for frequency subtraction is known;
При равенстве частот входных им-пульсов в реверсивном счетчике запись ваетс какое-то число, которое будет пульсировать около одного уровн . При неравенстве частот входных импульсов происходит монотонное увеличение или уменьшение числа, записанного в счегчике . Число, записанное в счетчике, измен етс в диапазоне от нул до максимального значени . При достижении гранил диапазона число, записанное в счетчикеWith equal frequencies of input pulses in a reversible counter, a record is written which will pulsate around one level. When the frequency of the input pulses is unequal, a monotonous increase or decrease in the number written in the switch occurs. The number recorded in the counter varies from zero to the maximum value. When the range reaches the limit, the number recorded in the counter
не измен етс , поэтому импульсы BXOIVной частоты, которые не мен ют COCTOS ни счетчика, направл ютс на выхогоые шины. Таким образом, происхорит формирование сигнала разности частот входных импульсов.does not change, so the BXOIV frequency pulses, which do not change the COCTOS or counter, are sent to the outgoing buses. Thus, the formation of the signal of the frequency difference of the input pulses will occur.
Дл правильного функционировани этого устройства необходимо иметь две несовпадающие тактовые последовательности импугалов какого-то внешнего генератора. Необходимость использовани блоков временной прив зки дл предотвращени счетчика значительно усложн ет данное устройство дл вычитани частот.In order for this device to function properly, you must have two mismatched clock sequences of the impugals of some external generator. The need to use temporary lock blocks to prevent the counter makes the device for frequency subtraction much more difficult.
