  • Patent number: 4634983
    Abstract: The described circuit arrangement converts an alternating current signal into a binary signal when the level of the alternating current signal exceeds an initial threshold voltage. During the period of time in which the alternating current signal is delivered, the threshold voltage is reduced. If the level of the alternating current signal falls short of the reduced threshold voltage, then the delivery of the alternating current signal is interrupted and the threshold voltage is again increased to its initial value. This hysteresis during switch-on and switch-off of the binary signal results in either an error-free binary signal being supplied or no binary signal at all.
