Abstract
In a process variable transmitter, a sensor signal is sampled, using a clock signal, at a sensor sampling frequency. Interference is also sampled at the sensor sampling frequency. A comparison is made to determine whether the interference at the sensor sampling frequency or harmonics of the sensor sampling frequency exceed a threshold level. If so, the clock signal is changed to adjust the sensor sampling frequency away from the frequency of the interference.
