80W Broadcast FM Stereo Transmitter
80W Broadcast FM Stereo Transmitter SchematicThe two single-ended line level audio signals enter through feedthrough capacitors, and are greeted by a low pass LC filter to get rid of any RF that might be on them. In each channel there is a buffer stage, and then a combination of pre-emphasis and soft-limiting step. The advantage of limiting and pre-emphasis in one step is to avoid heavy

AN7415 FM stereo Demodulator
The circuit shown below is from a PLL FM stereo demodulator designed depending on the AN7415. C1 is the coupling capacitor input that blocks any DC voltage present on the multiplexed signal input. LED D1 is a LED indicator and R1 is its current limiting resistor. C4 and C5 seem to be decoupling capacitors in DC for the left and right output channels.C2 and C3 to be noise bypass capacitors for the
