DESCRIPTION

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.
