Regulating system for radio controlled clock - uses correction device in digital section between receiving section and manual adjustment

摘要

The control system for a remote controlled clock includes manual adjustment. After receiving and monitoring the correct time, connection between the manual adjustment and the clock is blocked. The relationship between the manually entered data and the receiving function is established in the digital part. When a sufficiently satisfactory correlating value has been achieved, a synchronising signal is generated and for establishing the relationship, the unknown part of the time telegram is used and/or the adaptation process is set in operation. A high value quartz filter can be incorporated in the analog section. The digital and analog parts are separated by a screening plate. The screening, the correlating system, the highly selective filter and the manual adjustment can be combined.
