    • A first band-pass filter extracts, from a first sound intermediate frequency signal, a signal having a frequency in the vicinity of a center frequency of the first sound intermediate frequency signal. Then, a mixer down converts a signal extracted by the first band-pass filter to a second sound intermediate frequency signal. A low-pass filter extracts, from the second sound intermediate frequency signal, a signal having a frequency in the vicinity of a center frequency of the second sound intermediate frequency signal or a lower frequency. With such an arrangement, FM detection can be performed preferably even if the frequency of the first sound intermediate frequency signal is deviated.
    • 第一带通滤波器从第一声音中频信号中提取具有第一声音中频信号的中心频率附近的频率的信号。 然后,混频器将由第一带通滤波器提取的信号转换成第二声音中频信号。 低通滤波器从第二声音中频信号中提取具有在第二声音中频信号的中心频率附近的频率或较低频率的信号。 通过这样的布置,即使第一声音中频信号的频率偏离,也可以优选进行FM检测。
