Patent ID: 6845134

Claim:
An arrangement for receiving a digital signal from a transmission medium, the arrangement comprising: input means for receiving a signal from the transmission medium, asynchronous sampling means for sampling an analog signal so as to obtain a first signal having asynchronous samples, variable equalizer means having an input coupled to the input means, a control signal input for receiving a control signal, and an output for supplying an equalized signal, equalizer control signal generator means having an input, and an output for supplying an equalizer control signal, which output is coupled to the control signal input of the equalizer means, signal detector means, having an input coupled to the output of the variable equalizer means, and an output for supplying the digital signal, the signal detector means being adapted to detect the digital signal from the equalized signal, an output terminal coupled to the output of the signal detector means, for supplying the digital signal, characterized in that: the input of the equalizer control signal generator means is adapted to receive a second signal having asynchronous samples, the equalizer control signal generator means comprises detection means for detecting the instant at which the second signal crosses a predetermined signal value, so as to obtain a detection signal, and means for, in response to said detection signal, deriving the equalizer control signal from at least one asynchronous sample value of the second signal at either side or the instant at which the second signal crosses said predetermined signal value, said equalizer control signal being derived from said at least two samples by means of an operation equivalent to arithmetically combining said at least two asynchronous sample values.
