Description
Известны способы апредёлени кратности частот электрических колебаний посредством -наблюдени на экране электронно-лучевой трубки. Наиболее распространенным способом вл етс способ наблюдени на экране фигур Лиссажу. Подобный способ удобен, есл.и кратность контролируемых частот не превышает .15 в случае гармонических сигналов. При большей кратности наблюдени сильно затруднены, т. к. крайние витки фигуры Лиссажу станов тс трудноразличимым.и.Methods are known for determining the frequency ratio of electrical oscillations by means of observing on a screen a cathode ray tube. The most common method is to observe Lissajous figures on the screen. This method is convenient, if the frequency multiplicity of monitored frequencies does not exceed .15 in the case of harmonic signals. With a greater frequency of observation, it is very difficult, since the extreme windings of the Lissajous figure become difficult to distinguish.
Усложнением устройства мож о добитьс четкости изображени фигур до кратности .контролируемых частот, равным 25.By increasing the complexity of the device, we can achieve sharpness in the image of the figures up to a frequency of controlled frequencies equal to 25.
Описываемый способ олределени крарности частот позвол ет контролировать частоты с кратност ми пор дка 100. Дл этого колебани высокой частоты модулируют колебани ми низкой частоты. В качестве модул тора может быть использован, например, шунтовой преобразователь .на полупроводниковом триоде. Модулированные колебани подают на вход катодного осциллографа. Отношение (кратность ) частот определ ют путем подсчета числа .импульсов высокочастотных колебаний за период низкочастотных колебаний. Изображение ам.плитудно-модулИ1рованного колебани на экране трубки неп одвижно, а поэтому отсчет числа импульсов не представл ет затруднений.The described method of frequency limiting allows control of frequencies with multiples of the order of 100. For this, high frequency oscillations are modulated by low frequency oscillations. As a modulator, a shunt converter can be used, for example, on a semiconductor triode. Modulated oscillations are fed to the input of a cathode oscilloscope. The ratio (multiplicity) of frequencies is determined by counting the number of pulses of high-frequency oscillations over a period of low-frequency oscillations. The image of the amplitude-modulated oscillation on the screen of the tube is not monotonous, and therefore the counting of the number of pulses presents no difficulty.
Описанный способ измерени кратности частот электрических колебаний может найти широкое применение в радиотехиике, технике проводной св зи, автоматике и т. п.The described method of measuring the frequency of electric oscillations can be widely used in radio engineering, wireline engineering, automation, etc.
