DESCRIPTION
The device includes a high performance audio pro-
cessor with 7 bands equalizer and spectrum analyzer
plus a stereo decoder-noiseblanker. The whole low
frequency signal processing necessary for state-of-
the-art as well as future car radios is therefore provid-
ed. The digital control allows a full programming not
only of the audioprocessor and filter characteristics
but also in the stereodecoder part especially for the
adaptation to different IF-devices.
