を持つ正弦波発振器に加えて同期発振せしめ、この発振
出力と、前記定振幅信号とを掛算器に加えて差信号を復
調することを特徴とするｆｉＭｘテレオ放送の差信号復
調器。A signal obtained by limiting the amplitude of the N stereo signal to a constant amplitude is applied to a sine wave oscillator having a piezoelectric element to cause synchronous oscillation, and this oscillation output and the constant amplitude signal are added to a multiplier to demodulate a difference signal. A difference signal demodulator for fiMx telecasting.
