Description
1-1зобретение отиоситс к области электроизмерительно техники.1-1 acquisition of Otoshits to the field of electrical measuring equipment.
Известное устройство дл измерени разности частот следовани импульсов, содержащее формирователь разности периодов, ключ и счетчик 1миульсов, характеризуетс пониженным быстродействием.A known device for measuring the difference in pulse frequency, which contains a period difference former, a key and a 1-pulse counter, is characterized by a slower response time.
Предлагаемое устройство отличаетс от изнестны .х тем, что оно снабжено иеремнол ителел1 частот, входы которого соединены с входами формировател разности периодов, а выход- с входом ключа, управл ющий вход которого подключен к выходу формировател разности периодов, а выход - к входу счетчика ИМПуЛЬСОВ.The proposed device differs from external one in that it is equipped with a frequency frequency switch, the inputs of which are connected to the inputs of the period difference generator, and the output is with a key input, the control input of which is connected to the output of the period difference generator, and the output - to the input of a pulse. .
Такое выполнение устройства позвол ет повысить его быстродействие.Such an embodiment of the device makes it possible to increase its speed.
На чертеже показана блок-схема описываемого устройства, состо щего из формировател У разиости периодов, перемиожител частот 2, ключа 3 и счетчика импульсов 4.The drawing shows a block diagram of the described device, consisting of a driver, a period gap, a frequency intermixer 2, a key 3, and a pulse counter 4.
Устройство работает следующим образом.The device works as follows.
Р1сследуемые сигналы с периодами TI и 7-2 поступают одновременно на входы формировател II иеремножител частот. Формирователь / вырабатывает временной интервал: .. На врем этого интервала открываетс ключ 3 и частота / / -/2- с перемножител частот 2 поступает на счетчик -/.P1 investigated signals with periods TI and 7-2 arrive simultaneously at the inputs of the former of the frequency multiplier II. The driver / produces a time interval: At the time of this interval, the key 3 is opened and the frequency / / - / 2- from the frequency multiplier 2 is fed to the counter - /.
Результат к концу измерени , врем которого не превышает сумму периодов TI и 7о, определ ют выражением: : Т-1г1-2-к /-пThe result at the end of the measurement, the time of which does not exceed the sum of the periods TI and 7 °, is determined by the expression: T-1y1-2-k / -n
Предмет изобретени Subject invention
Устро1 1ство дл измерени разности частот следовани имнульсов, содержащее формирователь разностн нериодов, ключ и счетчик импульсов , отличающеес тем, что, с целью повышени быстродействи , оно снабжено перемножнтеле .м частот, входы которого соединены с входами формировател разности периодов , а выход - с входом ключа, управл ющий вход которого подключен к выходу формировател разности периодов, а выход--к входу счетчика ИМПУЛЬСОВ.A device for measuring the difference in the frequency of the follow-up of pulses, containing a differential driver, a key and a pulse counter, characterized in that, in order to improve speed, it is equipped with a frequency multiplier, whose inputs are connected to the inputs of the period differential generator, and the output is connected to the input the key whose control input is connected to the output of the period difference generator, and the output to the input of the PULSE counter.
