摘要:
A appliance (100) having a receiver (324) capable of receiving and a decoder (314) capable of decoding a time signal (400) into a time value. A clock (308) in the appliance (100) is updated or set with the received time value and an indicator (104) is activated to notify consumers that time synchronization to a time signal has occurred. The decoder (314) from the decoded time signal (400) is able to identify leap years and changes to and from daylight savings time.
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.
