Abstract (en)
[origin: EP0619559A2] Invention relates to an integrated analog-digital boundary interface for time multiplexed communication systems. The analog-digital boundary interface consists of an integrated AFE circuit (17) in which functioning of A/D and D/A converters are combined. The solution according to the invention is efficient and advantageous from the point of view of interference control and complexity. <IMAGE>
