In this paper, after analysing the soft threshold function, the smoothness threshold function is proposed by modifying the soft threshold function.
本文在分析软阈值函数的基础上通过对软阈值函数进行修正，提出了平滑阈值函数。
Methods: Filtering different noises in ECG signals by adopting threshold function of soft-and-hard threshold tradeoff and self-adapting threshold policies.
方法：采用软、硬阈值折衷的阈值函数及自适应的阈值策略对心电信号中的不同噪声进行滤除。
