To reconstruct data transmitted over a transmission path, for example a
cable, the corresponding signal received by the receiver is firstly
amplified and subsequently made discrete by means of an A/D-converter
(6), in order to obtain a suitable digital signal, whereby the signal
amplified for this purpose is scanned with a relatively low sampling
rate, which can frequently lie in the Nyquist range or can be even less
than the Nyquist frequency. Subsequently the signal made discrete in this
way is filtered by means of a digital high pass filter (8) and equalized
by means of a digital cable approximation filter (9) to compensate any
distortion occurring during the transmission over the transmission path.
By means of a phase locked loop (14, 18) a regenerated clock (CLK) and
synchronous with this clock the originally transmitted data (DATA) is
recovered from the digital signal processed in this way.
