    摘要： In order to shorten the transient recovery duration, the phase-locked loop has a voltage-controlled oscillator providing an oscillator signal to a first frequency divider. The first frequency divider divides the frequency of the oscillator signal, generates a first divider output signal therefrom, and passes it to a phase comparator during the transient recovery duration of the phase-locked loop. Furthermore, a unit is provided, which, after the transient recovery duration of the phase-looped loop, divides the frequency of the first divider output signal and passes it to the phase comparator. The phase comparator compares the first divider output signal with a first reference signal during the transient recovery duration. The phase comparator compares the divided divider output signal with a second reference signal after the transient recovery duration. The output of the phase comparator is connected to the voltage-controlled oscillator via a controllable charge pump.

    摘要： A method for detecting the beginning of the dips of the amplitudes in the output signal of a time signal receiver identifying the beginning of a second in the time signal. The output signal of the receiver for the time signals is sampled N-times per second. The sampled values are stored to respective cells of a memory field with N cells. In the memory field a mean signal curve for the time interval of one second is generated over a period of several seconds. A minimum valve and hence the beginning of the seconds in the time signal is determined from the mean signal curve valves in the memory cells.

    摘要： A method is described for detecting the time messages in the faulty signal of a time-signal transmitter comprising the steps below. Probabilities are assigned to the received information/bits as they are received and whose sign specifies the value of the bit and whose numerical value indicates the certainty of reception. Except for the bits designating the minute information, the probabilities of successive time messages are totaled with time correctness in a one-dimensional memory field. From the totaled probabilities, a reduced time message is reconstructed that initially contains no information on the minutes. If the reconstructed time message does not change over two successive time intervals, and if preset minimum values for the number of probabilities are exceeded for all bits, then the reduced time message is recognized as being correct. The minutes are determined separately and added to the time message recognized as being correct.

    摘要： In a method for calibrating or aligning a multistage selective amplifier including an oscillator circuit and at least one tuning circuit, the tuning voltages respectively necessary for aligning the respective tuning circuits to the required receiving frequency are calculated directly from a mathematical relationship between the respective tuning voltage and the oscillator voltage. In order to achieve this, a characteristic multiplicative coefficient and a characteristic additive factor for each tuning circuit are stored in a memory upon manufacturing or switching on the device. In order to select a desired receiving frequency, the respective stored values as well as an oscillator voltage are provided to an amplification circuit, which correspondingly amplifies the oscillator voltage by the multiplicative coefficient and the additive factor and then provides the resulting output value as a tuning voltage to the respective tuning circuit. Thus, all necessary tuning voltages can be determined from the two respective stored values per tuning circuit, as necessary for selecting any desired receiving frequency.
