Abstract: The described techniques address the issues of latency and lengthy processing times associated with conventional redundant sensor measurement systems that rely upon digital transmission protocols by implementing a diverse analog sensor interface architecture. The described architecture may advantageously use a number of sensor measurement paths that may be independent of one another or share any suitable number of common components to provide varying levels of redundancy. The analog interfaces may provide signal diversity with respect to the use of different types of analog transmission protocols, which may include different signaling interfaces (e.g. differential versus single-ended), different transmission interfaces (e.g. voltage versus current interfaces), and/or the use of different signalization schemes.
