FDM stereo decoder

Posted on Aug 9, 2012

For other input structures see Figures 6 to 11; shown here with PC-filter (Figure ß). The micropoco capacitor has a temperature coefficient of 125.10`6i 60.10` k`1. In simplified circuits a fixed resistor (e.g. 620k) can be used for a guaranteed switching level Of < 16mV. Either the LEO circuit or an external stereo indicator can be used.
