Abstract
PURPOSE: To make automatic time correction by providing a filter where only signals of the same frequency as a time signal are allowed to pass and then by supplying its output to a second directing reset-to-zero circuit through a crest discrimination circuit and time signal discrimination circuit for second correction.
CONSTITUTION: The count content of counter 4 of watch circuit 1 is displayed by display unit 6 through display driver circuit 5. Further, a time signal is received by receiver 7 and filter 9 allows a component equal in frequency to the time signal to pass through; and this signal is supplied to crest discrimination circuit 10 for conversion into a binary signal, which is led to time signal discrimination circuit 11. Then, discrimination circuit 11 discriminates a time pattern to send out a pulse based upon it and 30-second directing reset-to-zero circuit 12 resets the second- counter of counter 4 and also corrects display contents. Therefore, second correcting and start operations are automatized to simplify correcting operation.
