摘要
A method includes sensing a process parameter to generate a sensor signal that includes a process signal and line noise components (102), digitizing the sensor signal at a sample rate (102), detecting line noise zero crossings in the sensor signal (104), determining a line noise frequency as a function of the detected line noise zero crossings (106), and adjusting the sample rate as a function of the line noise frequency to reduce an impact of line noise on the digitized sensor signal (110).
