Description
Предлагаетс гармонический анализатор кривых, задапиих в графической форме, позвол ющий уменьшить габариты известных нриборов, прсдназначеиных дл аналогичных целей, и унростить их иастройк Анализатор содержит устройство записи кривой на магнитную бесконечную ленту, лентопрот жный механизм и воспроизвод щую систему. Воспроизвод щей головкой служит обычна магнитна i-оловка, в зазор которой iiOMcHieH примененный в качестве узкоиолосного фильтра датчик Холла, обладающий свойством избирательио линейно детектировать иапр жение , поданное на его вход, только той частоты, котора совпадает с частотой магнитиого нол , в котором иаход.итс датчик. Датчик Холла подключен к звуковому генератору.A harmonic analyzer of curves, graphically presented, is proposed to reduce the dimensions of known instruments for similar purposes, and to adjust them to tuning. The analyzer contains a device for recording a curve onto a magnetic infinite tape, a tape drive mechanism and a reproducing system. The reproducing head is the usual magnetic i-tin, in the gap of which iiOMcHieH the Hall sensor used as a narrow-band filter, which has the property of selectively detecting linearly and the voltage applied to its input, is only that frequency that coincides with the frequency of the magnetic zero in which the input. its sensor. The Hall sensor is connected to a sound generator.
При иодаче на вход датчика нанр жеии со звукового генератора с ланным 1зменением частоты, при вращении ленты с записью заданной кривой иа выходе датчика будут носледовательно по вл тьс напр жени пропорциональные /У,„- /„/, где Я,,; -амгтлитуда магннтного нол частоты i содержащейс в записанной кривой, а /„j -амнлнтуда тока же частоты, проход щего через датчик от звукового генератора. Выходное ианр жеиие датчика измер етс чувствительным прибором посто нного тока.During iodation, the input of the sensor is from a sound generator with a frequency change, while rotating the tape with recording a predetermined curve and proportional voltage to the sensor, voltage proportional to / U, „- /„ /, where I ,,; The magnetic zero frequency of frequency i contained in the recorded curve, and / j the current frequency of the same frequency passing through the sensor from the sound generator. The sensor output is measured by a DC sensing device.
