A device for position sensing comprises sensing means arranged for producing at least two sensor signals, and a signal construction unit. The signal construction unit comprises selection means for selecting in a serial way one of at least two time-synchronous signals, sampling means for sampling a selected time-synchronous signal at given sampling instants, storage means for storing sampled data representing the selected time-synchronous signal and timing information indicating which of the given sampling instants were used to obtain the sampled data, and processing means for determining at one of the given sampling instants a value for at least one of said time-synchronous signals that was not sampled at the one given sampling instant by performing an interpolation using data values of the at least one time synchronous signal stored in the storage means and obtained at another point in time than the one given sampling instant.

A sensor interface operates to communicate a sensed quantity along one or more processing pathways and in different data representations. The signal representations can be swapped along one or more locations of the signal processing branches. These branches are independent from one another and combined at an interface component for transmission along a single path or node for a control unit.
