Abstract
A receiving circuit for a radio-wave clock broadcast wave having a frequency converter that converts a received signal of the radio-wave clock broadcast wave into a signal of a frequency in the bandwidth of an AM radio broadcast. The converted-into signal is input to a first high frequency amplifier of an AM radio receiver of a heterodyne type comprising the amplifier, an oscillator, a frequency mixer generating a signal of an intermediate frequency, an intermediate frequency amplifier amplifying the signal of the intermediate frequency, and a detector. Time correction is performed on the basis of a demodulated signal of the radio-wave clock broadcast wave output from the detector.
