Claim 2:
3. The method according to claim 2, wherein using the maximum noise amount and the minimum noise amount as the interpolation condition, and performing the interpolation calculation on the level amplitude of the sampled electrical signal based on the initial noise ratio parameter to obtain the first noise amount comprise:
obtaining a tolerable-noise amount σG associated with the sampled electrical signal at a preset sampling point;
determining a maximum noise amount σmax associated with the electrical signal at the maximum level according to the following:
σmax=MσG, wherein M represents the initial noise ratio parameter;
determining the minimum noise amount associated with the electrical signal at the minimum level is σG;
performing quantization between the maximum level and the minimum level to obtain N level values, wherein the N level values are all between the maximum level and the minimum level, and N is a positive integer;
determining N noise amounts respectively associated with the N level values according to a preset interpolation algorithm;
determining that the level amplitude of the sampled electrical signal is a first level value in the N level values; and
obtaining a first noise amount associated with the first level value based on an association between the N level values and the N noise amounts.
