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.
