Description
(54) УСТРОЙСТВ 5) ДЛЯ ВОСПРОШВЕДЕНИЯ СИГНАЛОВ С МАГНИТНОГО НОСИТЕЛЯ(54) DEVICES 5) FOR REPRODUCING SIGNALS FROM A MAGNETIC MEDIA

Изобретение относитс к области приборостроени и может быть использовано в аппаратуре магнитной записи и воспроизведени частотно-модулированных сигналов.The invention relates to the field of instrumentation and can be used in magnetic recording and reproducing equipment of frequency-modulated signals.
В известных устройствах воспроизведени демодул ци осуществл етс путем преобразовани частотно-модулированных сигналов ЧМ в частнотноимпульсно модулированные сигналы, при чем это преобразование сопровождаетс умножением несущей частоты, что уменьшает величину комбинационных помех , а следовательно, повьшает достоверность воспроизводимой информацииIn known playback devices, demodulation is carried out by converting frequency-modulated FM signals into frequency-pulse-modulated signals, and this conversion is accompanied by multiplication of the carrier frequency, which reduces the amount of combination noise, and therefore increases the reliability of the reproduced information

Однако не всегда помехоустойчивость бывает достаточной у этого устройства .However, not always noise immunity is sufficient for this device.
Наиболее близким по технической сущности и достигаемому результату вл етс устройство дл воспроизведени сигналов с магнитного носител , содержащее последовательно соединенные магнитную полоску, усилитель, полосовой фильтр, блок дифференцировани , первые амплитудный ограничитель, фильтр нижних частот, сумматор и регулируемый усилитель, последовательно соединенные с выходом полосового . фильтра, вторые амплитудный ограничитель , фильтр, оконечный сумматор, выход которого св зан со входом оконечного фильтра нижних частот, а так0 же п суммирующе-вычитающие ступени, (и - целое число), кажда К-а из которых (К-номер ступени состоит из 3-2 суммирующих цепей, содержащих свой сумматор, св занный выходом The closest in technical essence and the achieved result is a device for reproducing signals from a magnetic carrier, containing serially connected magnetic stripe, amplifier, band-pass filter, differentiation unit, first amplitude limiter, low-pass filter, adder and adjustable amplifier, serially connected to the output of the bandwidth . filter, second amplitude limiter, filter, final adder, the output of which is connected with the input of the final low-pass filter, as well as n summing-subtracting steps (and is an integer), each of which is K (K-number of step) of 3-2 summing circuits containing their adder connected by the output
