Abstract
Methods and apparatus for combining redundant signals to generate outputs signals with enhanced accuracy and/or risk level. In embodiments, first signals are generated by a first transducer and second signals are generated by a second transducer. In other embodiments, first signals are generated by a first die and second signals are generated by a second die. An amount of overlap between error distributions of the first and second signals can be used to detect failure and/or indicate risk of failure.
Claims45
A method, comprising:
- receiving first signals from a first signal source;
- receiving second signals from a second signal source, wherein the first and second signals are redundant;
- and
- combining the first signals and the second signals to generate a first output signal from the first signals, a second output signal from the second signals, and a third output signal from the first signals and the second signals.

A system, comprising:
- a first signal source configured to generate first signals;
- a second signal source to generate second signals, wherein the first and second signals are redundant;
- and
- a signal processing module configure to combine the first signals and the second signals to generate a first output signal from the first signals, a second output signal from the second signals, and a third output signal from the first signals and the second signals.
