Description

Известны способы получени  произведени  амплитуд двух гармонических колебаний одинаковой частоты и косинуса угла сдвига фаз между ними. Искома  величина в этих способах выдс.т етс  при иомоши квадратичиых элементов или электродинамических приборов.Methods are known for obtaining the product of the amplitudes of two harmonic oscillations of the same frequency and the cosine of the phase angle between them. The required value in these methods is indicated by the presence of quadratic elements or electrodynamic devices.

Отличие описываемого способа от извсст)1ых состоит в том, что. с целью получе1Н1  нроизведеин  амплитуд колебани н косинуса угла между иими, используют двойное преобразование частоты с применением низкочастотного всномогате.чьного генератора.The difference between the described method of izvst) 1th is that. in order to obtain 1 N1 output of amplitudes of oscillations and cosine of the angle between them, double frequency conversion using a low-frequency oscillator of a high-frequency generator is used.

Если на преобразователь частоты подать две частоты fi и f2 (f - частота всномогательиого генератора; 12 - частота одного из колебаний , подлежаипгх умиожению), то на выходе его будут присутствовать частоты fi, 2 и 2:t: fi- Гармониками BE icHjero пор дка из-за их малости можно пренебречь. Разумеетс , что f| чГ fo. Эти иапр л ени , за исключением напр жени  частоты fi, задерживаемой фильтром, поступают на BTOpoii преобразователь. Кроме того, на второй преобразователь подают напр жение частоты 1з ts (1з - частота второго колебани , подлежащего умножению). Данное напр жение подаемс  через фазовраН1 ,атель. На выходе второго преобразовани , кроме основных частот, присутствуют две комбинационные частоты, составл ющие ток частоты fi. Это: f2 - fs + fi fi и fr,- (Ь--Ь) fi- Напр жени  с частотой fi выдел ют с помощью фильтра и усиливают. Амплитуда выходного напр жени , снимаемого с усилител , пропорциональна произведению амплитуд колебаний с частотами f л f,.; и косинуса угла сдвига фаз между иими.If two frequencies fi and f2 are applied to the frequency converter (f is the frequency of the omnipotent oscillator; 12 is the frequency of one of the oscillations to be moderated), then its output will contain the frequencies fi, 2 and 2: t: fi- Harmonics BE icHjero because of their smallness can be neglected. Of course, f | hg fo. These transducers, with the exception of the voltage fi, delayed by the filter, are fed to the BTOpoii converter. In addition, a voltage of 1s ts is applied to the second transducer (1h is the frequency of the second oscillation to be multiplied). This voltage is supplied through a phase switch. At the output of the second transformation, in addition to the fundamental frequencies, there are two combination frequencies, which constitute the current frequency fi. These are: f2 - fs + fi fi and fr, - (b - b) fi- Voltages with frequency fi are extracted with a filter and amplified. The amplitude of the output voltage taken from the amplifier is proportional to the product of the amplitudes of the oscillations with frequencies f l f,.; and the cosine of the phase angle between them.
