Receiver for digital signals in line code

Claim 1

A receiver for receiving a line signal constituted by a first digital signal, said first digital signal being encoded in a line code and representing a digital version of an analog information signal, the receiver comprising: an input for receiving the line signal; a decoder coupled to said input and arranged for converting the line signal into said first digital signal; a digital-to-analog converter comprising an input; means for coupling the input of the digital-to-analog converter to said decoder; characterized in that: the receiver further comprises: the line-code violation detector also coupled to the input of the receiver and arranged to detect whether the line signal deviates from the line code; and a generator for generating a second digital signal; wherein said coupling means comprises a first input coupled to said decoder, a second input coupled to said generator, an output coupled to said digital-to-analog converter, and a control input coupled to said line-code violation detector for selectively coupling said first or second input to said output, whereby when said line-code violation detector indicates a deviation from said line-code, said generator is then coupled to the input of said digital-to-analog converter.
