Description

из вослроиавооимых с магнитного носител  сигналов путем их усилени  и формировани  в моменты достижени  воспроизводимыми сигналами лорогового уровн  лапр жеиа  выдел ют напр же-ние огибающей воспроизводимых сигналов , пропорционально преобразуют это напр жение и используют его в качестве порогового напр жени .from amplifying signals from a magnetic carrier, by amplifying them and forming a reproducible signal at a time when the signal reaches the logical level, the stress of the envelope of the reproduced signals, proportionally transform this voltage, and use it as a threshold voltage.

Ка чертеже приведен пример реавдзации предлагаемого способа выделени  импульсов.The drawing shows an example of the revavdization of the proposed method of pulse extraction.

Устройство, реализующее данный способ , содержит усилитель воспроизведени 1, детектор 2, пропорциональный пре образователь 3i выполненный, например, на делителе напр жени , и пороховый элемент 4. Входом  вл етс  шина А, а выходом - шина В,A device implementing this method contains a playback amplifier 1, a detector 2, a proportional transducer 3i made, for example, on a voltage divider, and a powder element 4. The input is bus A, and the output is bus B,

Воспроизводимый головкой (на чертеже не показана) сигнал поступает по шине А на усилитель 1 и далее на детектор 2, который выдел ет огибающую сигналов. Затем напр жение огибающей поступает на пропорциональный преобразователь 3, который вырабатывает напр жение , соответствующее уровню напр жени  сигнала при максимальной производной воспроизводимого сигнала, которое обеспечивает наиболее веро тное и точное воспроизведение.A reproducible head (not shown) sends the signal through bus A to amplifier 1 and then to detector 2, which highlights the envelope of the signals. Then, the envelope voltage is supplied to the proportional converter 3, which produces a voltage corresponding to the voltage level at the maximum derivative of the reproduced signal, which provides the most probable and accurate reproduction.

Уровень максимальной крутизшл сиг- .нала равен его амплитуде, умноженнойThe level of the maximum slope of the signal is equal to its amplitude multiplied

на коэффициент lATe, Так как па /азитна  амплитудна  модул ци  сигналов воспроизведе1щ  в аппаратуре Mai-iuiTной записи  вJшeтc  низкочастотной но сравнению с полезным сигналом, то использование преобразованной огибающей в качестве порогового уровн  обеспечивает эффективное слеже1ше за изменением амплитуды.by the coefficient lATe. Since the PA / AzIT amplitude modulation of the signals is reproduced in the MI-IUIT recording equipment in JETS low frequency but compared to the useful signal, using the converted envelope as the threshold level provides an efficient follow up of the amplitude change.
