Description
(54) СПОСОБ ОПРЕДЕЛЕНИЯ ВРЕМЕННОГО РАССОГЛАСОВАНИЯ СИГНАЛОВ, ВОСПРОИЗВОДИМЫХ С МАГНИТНОГО НОСИТЕЛЯ . 489145 3 число И определйют, йбход иа заданной точности измерени временного рассогласовани . Таким образом, определение временного рассогласовани как среднего значени ве-g личии, обратных разност м смежных частот f, , позвол ет повысить точность измерений . Предмет изобретени Способ определени временного рассо4 тасовани сигналов воспроизводимых с магнитного носител , при котором на магнит- ный носитель предварительно записьюают испытательные сигналы, о т л и ч а. и и с тем, что, с целью повьоцени точности измерени , записывают ra iMoнические сигналы, дискретно измен их частоты, затем сигналы воспроизвод т, одновременно определ частоты, на ко . торых разность фаз сигналов кратна 2j, и определ ют среднее значение величин. обратных разност м смежных частот.(54) METHOD FOR DETERMINING THE TEMPORARY DISPOSAL OF SIGNALS REPRODUCIBLE BY A MAGNETIC MEDIA. 489145 3 and the number is determined by the given accuracy of the measurement of the time error. Thus, the determination of the temporal mismatch as the average value of the magnitude of the inverse of the difference between the adjacent frequencies f, makes it possible to increase the measurement accuracy. The subject of the invention. A method for determining the temporal dispersion of signals reproduced from a magnetic carrier, in which test signals are previously recorded on a magnetic carrier, as such. and so that, in order to measure the accuracy of the measurement, they record the ra iMonical signals, varying their frequencies discretely, then the signals are reproduced, simultaneously determining the frequencies, at which. Second, the phase difference of the signals is a multiple of 2j, and the average value of the quantities is determined. inverse differences of adjacent frequencies.
