-Ивоб|ретение относитс  к о бласти :приборостроеии , а (И менно к аппаратуре мапнитной залиои, работающей с вьсокой разрешающей способностью.- The exemption relates to the region: instrument-making, and (In particular, to the equipment of the field filling, working with a high resolution.

Известно, что, в aininapaType магнитной за1Ниси одним из основных видов помех  вл ютс  помехи, возни.кающие в результате дстонаЦНи движущихс  элементов аппарата.

Known to a number of devices, according to their yoV, they can be reduced to a certain degree by Kai caiMy inoMexy, as well as by its influence on the quality of recording and reproducing SIGNAL 01B ipfO | p; mation on magnetic media.

TaiKHC устройства имеют достаточно BbicoiKHe погреншости ЛЗ-за наличи  детонаЦИН . TaiKHC devices have enough BbicoiKHe tolerance for LZ due to the presence of detonation.

Цель изобретеии  - уменьшение погреш«остей ,, возникающих при детонации в меха изме перемещени  ма1гнитного носител .The purpose of the invention is to reduce the errors of the “spine,” arising from the detonation in the fur, the change in the movement of the magnetic carrier.

Это достигаетс  благодар  использоваклю цепочки, состо щей из последовательно соедииепных частотного дисифиминатора, гетеродина с его блокам управлени  и смесител , включенного между блшком вооироиз1ведени  и уз ко полоснь м выходным фильтром.This is achieved through the use of a chain consisting of a sequentially connected frequency frequency disperser, a local oscillator with its control units, and a mixer connected between each other and a narrow band output filter.

На чертеже показана блак-схе.ма описываемого устройства дл  фильт ращии электрических си1гиало1в, воспроизводи1мых с движущегос  мапнитного носител .The drawing shows the block diagram of the described device for filtering electrical sigals that are reproduced from a moving paper carrier.

Блок-схема содержит генератор / опорной частоты, блок 2 записи, магнитный носитель 3, блок 4 воопроиЗВедени , частотный дискриминатор 5, бло1К 6 управлепл  гетеродипом,The block diagram contains a generator / reference frequency, a recording unit 2, a magnetic carrier 3, a block 4 in question, a frequency discriminator 5, a block K 6 controlled a heterodip,

ВB1 along with the reference frequency signal on the BLOCK playback device. The frequency discriminator generates an ectransient notional, which is proportional to the magnitude of the change in the frequency of the aior signal, due to the influence of detonation. Further, the heterodyne etching unit generates its own signal, which changes the tuning frequency of a selection system consisting of a local oscillator, a mixer and a filter 9, in the proportional mode of detonation. AT

результате на выходе получаетс  отклиач на исследуемый сигнал с компенсацией вли ни  детонаиии.As a result, the response to the signal under investigation is obtained with compensation for the effect of detonation.
