Patent attributes
Improved sensing can include modified sampling and/or processing to improve performance against noise due to environmental variations and interference. In some examples, improved interference rejection can be achieved by sampling a sensor multiple times during settled periods. In some examples, the excitation signal and sampling window can be dynamically adjusted to satisfy drift and/or interference specifications based on various operating conditions or the operating environment. In some examples, drift performance can be traded off to improve interference performance. In some examples, improved immunity to environmental variations can be achieved by equalizing sensor outputs in accordance with characterization of the sensing system. In some examples, improved performance can be achieved by sampling the sensor continuously and using an optimized window function to improve performance against noise.
