A filter cell, method of deriving an echo component and an echo canceling system, bit pump and transceiver employing the same. In one embodiment, the filter cell includes a first summing node that receives a first input based on a signal sample that contains an echo component of an echo. The filter cell also includes a second summing node that receives a second input based on the signal sample. The filter cell still further includes a multiplier that employs outputs from the first and second summing nodes and a scaling factor to derive first and second outputs containing a remnant of the echo component.
