Description

В моменты равенства модулей частотно-модулированного сигнала на входах компаратора напр жений 3 генератор импульсов посто нной длительности вырабатывает сигнал, подаваемый на выходную шину 5.At the moments of equality of the modules of the frequency-modulated signal at the inputs of the voltage comparator 3, a constant-duration pulse generator generates a signal applied to the output bus 5.

Claims (2)

В предлагаемом устройстве за счет того, что задержка частотно-модулированного сигнала производитс  до формировани  его модул , в значительной степени уменьшены искажени  результата воспроизведени . Предлагаемое устройство может найти применение в аппаратуре точной магнитной записи и воспроизведени . Формула изобретени  Устройство дл  воспроизведени  с носител  магнитной записи, содержащее входную шину воспроизведенного частотно-модулированного сигнала, соединенную через формирователь 20 In the proposed device, due to the fact that the delay of the frequency-modulated signal is produced before the formation of its module, the distortion of the reproduction result is significantly reduced. The proposed device can be used in the equipment of accurate magnetic recording and reproduction. Claims An apparatus for reproducing from a magnetic recording medium, comprising an input bus of a reproduced frequency modulated signal connected via a driver 20 модул  частотно-модулированного сигнала с одним из входов компаратора напр жений , подключенного к входу генератора импульсов посто нной длительности, и линию задержки, отличаюш.еес  тем, что, с целью уменьшени  искажений результата воспроизведени , в него введен дополнительный формирователь модул  частотно-модулированного сигнала, включенный между вторым входом компаратора напр жений и выходом линии задержки, вход которой подсоединен к входной шине воспроизведенного частотно-модулированного сигнала. 15 Источники информации, прин тые во внимание при экспертизе: 1. Авт. св. № 409280, М. Кл. G 11В 5/04, 1971. a frequency modulated signal module with one of the inputs of a voltage comparator connected to the input of a constant-duration pulse generator, and a delay line characterized by the fact that, in order to reduce distortion of the reproduction result, an additional shaper of the frequency-modulated signal module is introduced into it connected between the second input of the voltage comparator and the output of the delay line, the input of which is connected to the input bus of the reproduced frequency-modulated signal. 15 Sources of information taken into account in the examination: 1.
