A two-chip digital car radio
Lionel Vogt, D. Brookshire, S. Lottholz, G. Zwiehoff · 2002
Car radio design has been dominated for years by analog signal processing. If digital signal processing is used in a car radio, it begins with the multiplex signal (audio frequency) where filtering and sound control gives new features to the radio. The concept of the two chip digital car radio goes beyond these features: digitization of the intermediate frequency (IF); and mixed-signal processing technology using embedded DSP coprocessors.
