The evolution of telecommunications towards an Integrated Services Digital Network (ISDN) offers new opportunities for signal processing applications. Recent progress in basic techniques, like perfect signal decomposition and reconstruction or Least Squares adaptive filtering, are crucial in that evolution. Beyond the emergence of new equipment, signal processing advances are paving the way for artificial intelligence techniques, which will accompany the information age promised by the ISDN. tion. A set of recommendations for the ISDN has been issued as Series I [21. Several areas of digital signal processing are important for the evolution of the ISDN, and particularly digital filters, adaptive filters, and signal analysis and recognition in connection with artificial intelligence techniques. To begin with, some aspects of several important applications are reviewed in the context of the ISDN evolution.
