DESCRIPTION
The device includes a high performance audiopro-
cessor and a stereodecoder-noiseblanker combina-
tion with the whole low frequency signal processing
necessary for state-of-the-art as well as future carra-
dios. The digital control allows a programming in a
wide range of all the filter characteristics. Also the
stereodecoder part offers several possibilities of pro-
gramming especially for the adaptation to different
IF-devices.
