Abstract
An apparatus for processing data, such as liquid level data in a motor vehicle containing a liquid storage tank, comprises a liquid level sensor for developing a signal indicative of instantaneous liquid level in the storage tank, circuitry for processing the instantaneous liquid level signal, including asymmetrical filtration of the instantaneous liquid level signal, to provide a process output signal, and a display apparatus for displaying an indication of the level of liquid in the storage tank in response to the process output signal.
