摘要： Time information is retrieved from time signals transmitted by a transmitter and received by a receiver. The retrieval relies on the examination of at least one time portion (86, 87, 88) within a time frame. The time portion has a duration shorter than the duration of the time frame (80-82), to reduce processing operations. The examination checks whether an amplitude of the time signal changed within a time portion. The amplitude change either up or down is then evaluated for the retrieval of the time information. A receiver for receiving the time signals includes components for preprocessing the received time signals thereby reducing the processing steps of a microprocessor connected to the output of the receiver.

摘要： When the current time data in current time counting device has been corrected on the basis of the current time data transmitted over radiowaves, it is judged whether or not an alarm time is present between the time data before correction and the time data after correction. If an alarm time is present, the user is informed of the alarm time. This avoids the problem of failing to inform the user of the alarm time at that day. Furthermore, the correspondence between the current time data in the current time counting device and the time data in different functional device is prevented from changing as follows when the current time data has been corrected on the basis of the received time data, the time data in the different functional device is also corrected as much as the same correction time, or while the different functional device is operating, the time correcting operation is prevented from being carried out even if the time correction timing has been reached.

摘要： In a radio controlled clock and a decoding method of a time code signal, the time code signal can be accurately decoded irrespective of the mixture of noises and the deterioration of a radio wave signal receiving situation, and arithmetic processing is simple. A standard time signal is received and the time code signal superposed on this standard time signal is sampled at an interval of 50 ms and is stored to a memory. The stored sampling data are formed as a list in a data group every one second (20 samples). The plurality of data groups formed as a list are added every each sampling point, and a point for maximizing an increase change of the adding result is set to a synchronizing point of the sampling. Further, the correlation of the sampling data group and a code template pattern is calculated and a code shown by the sampling data group is judged.

摘要： A transmitted time signal carries time information encoded bit-wise by signal variations in a succession of constant duration time frames, with at least one bit in each time frame. A signal quality is determined and allocated to a respective bit, e.g. depending on the extent of deviation of an actual duration from prescribed durations of a signal variation representing the bit. Thus, a respective signal quality may be allocated to a respective decoded data bit per time frame. Successive data bits can be categorized as interference-free or interference-burdened, and a signal quality of the received time signal can alternatively be determined from the number or ratio of the interference-free bits and the interference-burdened bits. A radio-controlled clock circuit includes a receiving circuit, a bit value decoding arrangement and a signal quality evaluating arrangement.

摘要： A transmitted time signal carries time information encoded bit-wise by signal amplitude variations in a succession of time frames. A method involves receiving and evaluating the time signal in a receiver to acquire the time information, and then outputting from the receiver an individual data bit respectively allocated to a respective time frame during or at the end of or immediately after the respective time frame. It is not necessary to store all the data bits of a complete minute telegram in the receiver before the evaluation. The successive data bits are used by a microprocessor downstream from the receiver to produce a time signal. A circuit arrangement for a radio-controlled clock includes a receiving antenna connected to a receiver circuit that incorporates a time information decoder for decoding the time information contained in the time signal. The decoder provides, at an output of the receiver circuit, the decoded data bit allocated to a time frame, already during, at the end of, or immediately after the end of that time frame.

摘要： The invention relates to a method for decoding transmitted information units by comparing a signal section containing an information unit with a number of reference functions. A reference function is assigned to every possible information unit and that type of information unit is considered to be recognized for which the smallest deviation is established between assigned reference function and signal section. In the method according to the invention, the reference functions are modified in accordance with the signal curve in the respective actual signal section. The modifications are appropriately calculated using a fuzzy controller.

摘要： In a detection circuit that a radio wave receiver for receiving a long wave standard radio wave includes, a circuit is constructed so as to cancel noise components by using a multiplier, a divider, a differentiation circuit and an adder on the basis of a signal obtained by shifting the phase of a carrier signal by 90 degrees, the carrier signal having the same frequency and the same phase as those of the carrier of a received signal outputted from a carrier reproduction circuit. Thereby, it is possible to certainly remove the noises in the vicinity of a received frequency.

摘要： The invention relates to a method for detecting the beginning of time messages in the signal received from a time-signal transmitter. The signal of the time-signal transmitter consists of a series of blanking intervals on a carrier signal in the seconds clock cycle in which blanking intervals of different length cause different information units to be transmitted (ZERO pulse, ONE pulse, frame pulse). A time message, comprising the information units transmitted over a period of one minute, contains the actual time information in coded form. The time message has areas/sectors with defined, constant information units and areas/sectors with variable contents that code the time information. A reference message is stored in a first area of memory that contains the defined, constant information units that are located in fixed areas/sectors. A number of successive information units corresponding to the length of a time message are stored in a second area of memory. The contents of the first area of memory are compared unit for unit with the second area of memory. If an error occurs during comparison, the reference message in the first area of memory is shifted by one unit with respect to the received information units and subsequently compared again until no error occurs. When agreement is established, the number of shifts is used to determine the beginning of the received time message.
