Abstract: The invention relates to a device for reading digital information which is stored as a bivalent state of a moving carrier, for example, the magnetization direction of a tape. Reading causes a differentiating effect. A coil of the read member constitutes, in conjunction with a parallel connected capacitor, a resonant filter having a mediocre Q factor, so that the signal components of comparatively high frequency are slightly amplified. The output of the resonant filter has connected thereto an amplifier. A branch line for comparatively low frequencies with a filter having a drooping amplitude/frequency characteristic is connected to the amplifier. A branch line for comparatively high frequencies in which a filter having a rising amplitude/frequency characteristic is included is also connected to the amplifier.
