Description
The device includes a high performance
audioprocessor and a stereo decoder-noise
blanker combination, with the whole low
frequency signal processing necessary for state
of the art, as well as future car radios. The digital
control allows a programming in a wide range of
all the filter characteristics. The stereo decoder
part also offers several possibilities of
programming, especially for the adaptation to
different IF devices.
