Abstract:
The present invention relates to receiver equipment with AC-coupled receiver circuits and AC coupling filters. A switch connected between a first stage and a second stage among the receiver circuits is adapted to switch from a high coupling corner frequency, for rapid settling of a signal during preparation of data reception, to a low corner frequency, for low signal distortion during data reception. The receiver circuits are adapted to use known properties in the signal to perform the switch at a time when the short term DC-components of the signal are as low as possible.
