BLOCK DIAGRAM
The device includes a high performance audioprocessor
and a stereodecoder-noiseblanker combination with the
whole low frequency signal processing necessary for
state-of-the-art as well as future carradios. The digital
control allows a programming in a wide range of all the
filter characteristics. Also the stereodecoder part offers
several possibilities of programming especially for the
adaptation to different IF-devices.
