Abstract
A rearview assembly includes a mounting structure for attaching to a vehicle. The mounting structure includes a housing that has a rearview element disposed inside for providing a driver of the vehicle with a view to the rear of the vehicle. The rearview assembly also includes a continuously variable slope delta encoder module in or on the mounting structure configured to generate a feedback signal. The rearview assembly also includes a pre-processing module on or within the mounting structure. The pre-processing module is configured to process a source signal and the feedback signal from the continuously variable slope delta encoder module, and to provide a pre-processed signal to the continuously variable slope delta encoder module based on the value of the source signal and the feedback signal.
