Abstract

In a transmission system a signal to be transmitted by a first node (2) is applied to an encoder (8) and is transmitted by a transmitter (10) to a second node (6). In the second node (6) the signal from the transmission medium (4) is received by the receiver (12) and passed to a selector (18), directly and via an interpolator (14). By delaying the decoding of the signal in the case transmission errors occur, which lead to missing frames, it becomes possible to complete the missing frames by interpolation.
