Low Cost AM FM Stereo Receiver
This was a National Semiconductor Application Note, now TI. – Low Cost IC Stereo Receiver. The LM3089 FM IF System does all the major functions necessary for FM processing, including a three stage amplifier/limiter...
Antenna-amplifier with BFT 12 for FM-range
The only way to improve the reception of FM-signals or particularly of stereo FM-signals under disadvantageous receiving conditions is to amplify the antenna signal. This should be made directly at the antenna, since the...
