Classification: CPC H | IPC H

Claim 15:
16. The apparatus according to claim 15, wherein the processor is further configured to:
obtain a tolerable-noise amount σG of the sampled electrical signal at a preset sampling point;
determine maximum noise σmax associated with the electrical signal at the maximum level in the following manner: σmax=MσG,
wherein M represents the initial noise ratio parameter;
determine the minimum noise amount associated with the electrical signal at the minimum level is σG;
perform 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;
determine N noise amounts respectively associated with the N level values according to a preset interpolation algorithm;
determine that the level amplitude of the sampled electrical signal is a first level value in the N level values; and
obtain a first noise amount associated with the first level value based on an association between the N level values and the N noise amounts.
