Description
В технике динамических измерении дл оиределени5 мгновенного значени частотномодулированного колебани примен ютс способы, основанные на использовании селективных колебательных систем, фигур Лиссажу, двухкаиального гетеродинировани и т. д. Эти способы не позвол ют зафиксировать момента времени, когда мгновенное значение измен ющейс частоты совпадает с onopHpii частотой.In the technique of dynamic measurements, methods based on the use of selective oscillatory systems, Lissajous figures, two-channel heterodyning, etc. are used to determine the instantaneous value of the frequency-modulated oscillation. These methods do not allow fixing the time when the instantaneous value of the varying frequency coincides with the onopHpii frequency .
Описываемое изобретение устран ет указанный недостаток путем использовани дл определени совпадени измер емой и опорной частот момента равенства нулю скорости изменени разности фаз измер емых колебаний и колебаний опорного генератора.The described invention eliminates this drawback by using to determine the coincidence of the measured and reference frequencies of the moment when the rate of change of the phase difference between the measured oscillations and the oscillations of the reference oscillator is zero.
Дл осуществлени предлагаемо-, го способа примен етс устройство, состо щее из фазового детектора, на выходе которого включен дифференцирующий элемент, соединенный с измерительным прибором.To implement the proposed method, a device is used consisting of a phase detector, the output of which includes a differentiating element connected to a measuring device.
Колебани измер емой частоты и колебани от опорного генератораOscillations of the measured frequency and oscillations from the reference oscillator
подаютс на вход фазового детектора , а момент равенства этих частот фиксируют по показани м выходного прпбора, отклонение стрелки которого равно нулю в момент равенства частот.are fed to the input of the phase detector, and the moment of equality of these frequencies is fixed according to the readings of the output device, the deviation of the arrow of which is equal to zero at the moment of equality of the frequencies.
Предлагаемый способ и устройство дл его оеуитествлени могу г найти применение в системах автоматического управлени и в измерительных установках.The proposed method and device for its determination can be used in automatic control systems and measurement systems.
