    摘要: A quadrature type FM demodulator device used, for example, in a television receiver, includes a band pass filter for filtering a sound intermediate frequency (SIF) signal input to the device. The output of the band pass filter is coupled through a filter circuit to an integrated circuit having a limiter amplifier and an FM detector to output a sound signal from the SIF signal.
