Description
В iHSBecTHbix системах воспроизведени управл ющего сигнала, состо щих из усилйтел воакроиаведе:-1и и дл.скриминатора ощибки, в качестве ислолнктельного механизма компенсации примен ют инерцион .ны.е и элехтромеха.н;.чегкие системы.In iHSBecTHbix reproduction systems of the control signal, consisting of amplifiers in video and video: -1i and for the error screamer, inertial and elechtromekh.n are used as the compensation mechanism; light systems.
Осс бе ностью предлагаеМОго способа Я зл етс то, что, с целью компенгаадик паразитной частотной модул ции вплоть до са;МЫХ низких частот 10-100 гц, з качестве исполнительного механизма коМПенсации прИМбн ют безынерционное эл актронное устройство-фазовый модул тор , создающий противололожную частотную модул дию, управл емый опе-циальным сигналом ощибки, дл получени которого при выполнении звукозаписи на отдельную дорожку ленты з аписываетс сигнал опорной частоты.Owing to the offer of the method I, I am angry that, in order to compensate for parasitic frequency modulation up to SA; low frequencies of 10-100 Hz, an inertialer electron device-phase modulator that creates an anti-negative frequency the module, controlled by the operative error signal, to obtain which, when performing audio recording, the reference frequency signal is recorded on a separate tape track.
На чертеже дана блок-схема устройства, с помощью которого осуществл етс предложенный способ. Здесь: 1-воспроизвод ща головка; 2 - усилитель воспроизведени ; 3-фазовый модул тор; 4 - оконечный усилитель; 5-головка воспроизведени сигнала опорной частоты, котора р-аополагаетэ точно против голозки /; 6-усилитель воспроизведени канала опорной частоты; 7--дискриминатор сигнала ошибки; S-звуколоситель; 9 дорожка сигнала; 10 - дорожка опорной частоты.The drawing is a block diagram of the device with which the proposed method is carried out. Here: 1-repro head; 2 - playback amplifier; 3-phase modulator; 4 - terminal amplifier; A 5-head reproducing signal of the reference frequency, which regulates exactly against the slug; 6-amplifier playback frequency reference channel; 7 - error signal discriminator; S-Sound; 9 track signal; 10 - track reference frequency.
Предмет изобретени Subject invention
Способ компенсации паразитной частотной модул ции при магнитной записи отлича ющийс тем, что, с целью компенсации указанной модул ции, в канале воспроизведени примен етс фазовый модул тор , создающий противофазную модул цию, управл емый специально выделенным сигналом ощибки.The method of compensating for spurious frequency modulation in magnetic recording is different in that, in order to compensate for this modulation, a phase modulator is used in the reproduction channel, creating an antiphase modulation controlled by a specially selected error signal.
