FM Stereo demodulation circuit with voltage dividing and multiplexing techniques

摘要: An FM stereo demodulation circuit comprises a resistor voltage dividing network having plurality of outputs; first switch analog switches which respectively couple the outputs to output terminal; second and control sequentially enables circuits over one cycle period subscarrier signal in response pilot an composite signal. The produce staircase-wave multiplying waveshape depends on setting resistance values resistors network. therein or removed therefrom prior is applied so that multiplied by accomplish demodulation.
