发明名称 Method for operation of a radio-controlled clock and radio-controlled clock for use in an environment subject to interference fields
摘要 A method for operation of a radio-controlled clock comprising a quartz-controlled clock synchronized by a time signal receiver with a time signal via a signal processor. In a common array with an additional device, such as a computer or television set, reception of the time signal is generally largely prevented by the interference effect of the additional device. In the method in accordance with the invention, the quartz-controlled clock is therefore synchronized with the time signal solely when the additional device is no longer generating an interference field. For this purpose, a detector is provided that recognizes the operating state of the additional device and permits synchronization of the quartz-controlled clock with the time signal only when the additional device is not generating an interference field, or if so only a reduced one. Furthermore, a radio-controlled clock is described that is suitable for operation by the method in accordance with the invention.
