TIME INFORMATION OBTAINING DEVICE AND RADIO-CONTROLLED TIMEPIECE

摘要

A time information obtaining device and a radio-controlled timepiece are shown. According to one implementation, the time information obtaining device includes a noise determining section and a reception cancelling section. The noise determining section determines whether noise mixed in a demodulated signal of a radio wave received within a predetermined unit of time is equal to or more than a predetermined threshold level. The reception cancelling section cancels reception of the radio wave when a number of times that the noise determining section determines that the noise mixed in the signal is equal to or more than a predetermined level is included at a percentage equal to or more than a predetermined percentage within a set time including a plurality of the units of time.
