Abstract: A method of reducing a water-wave noise for an analog to digital conversion includes performing sampling on an analog input signal; determining whether the analog input signal is interfered with by a periodic noise such that a water wave is generated; and executing one or both of the following steps when the analog input signal is interfered with by the periodic noise: adjusting a sampling frequency of the ADC, and adjusting a noise frequency of the periodic noise.
