2.2 External Noise

External factors, such as electromagnetic interference (EMI), noise, and power supply fluctuations, can degrade the performance of the ADC and ADC calibration. Electrical noise sources, including powerful radio frequency (RF) signals or power supply noise, can introduce errors and degrade the performance of the ADC, requiring a re-calibration to restore optimal and accurate measurements.
