Abstract
Systems and methods for sensor position measurements are provided. Aspects include receiving, through a first signal path, a first secondary signal from a first sensor and a built in test (BIT) signal, wherein the first signal path comprises a first multiplexer connected to a first filter, receiving, through a second signal path, a second secondary signal from the first sensor and the BIT signal, wherein the second signal path comprises a second multiplexer connected to a second filter, wherein the first signal path and the second signal path are connected to a third multiplexer, wherein the third multiplexer is connected to a first analog to digital converter (ADC), receiving, by a controller, an output signal from an output of the first ADC, and determining, by the controller, a position measurement for the first sensor based on the first secondary signal, the second secondary signal, and the BIT signal.
