Abstract
PURPOSE: To facilitate transmission to an externally manipulated timepiece, by using a microphone to change an audible signal corresponding to information, into a voltage and by performing A/D conversion, Fourier transformation, etc. to reproduce and detect the information.
CONSTITUTION: An audible signal of frequency corresponding to information is changed into a voltage by a microphone 1. The voltage is conducted through an LPF 2 and then changed into a digital signal by an A/D converter 3 on which sampling is effected by a prescribed frequency division output of a frequency divider 8. The digital signal is rapidly Fourier-transformed into a frequency information signal by a Fourier transformation circuit 4. The information is reproduced and detected through a frequency encoder 5. This results in facilitating transmission to an externally manipulated timepiece. According to this constitution, time correction or the like can be precisely effected by easy manipulation when set information is applied to a second, a minute and an hour counters 9W11 by a setting circuit 6.
