ABSTRACT:
Multiple redundant sensor signals are processed through an equalizing and selecting network which outputs the midvalue signal and eliminates all null offsets occurring among signals. Errors due to drift in a signal are minimized by bounding the output to the limits of the remaining redundant signals. Faults of both a high and low frequency nature are detected resulting in the isolation of the appropriate signal channel.
