snr的用法

Significant negative correlation between the PTT and SNR of DPOAE were found at various corresponding frequency points.

各相应频率点的纯音听阈值与DPOAE的信噪比值之间呈现明显的负相关，纯音测听与DPOAE检测结果表现出明显的一致性。

In theory of estimation with wavelet thresholding, the threshold adapting data can be calculated by minimum estimation of risk to improve the SNR of estimation.

根据小波阈值估计理论，通过最小化风险的估计，可计算自适应于数据的阈值，提高估计的信噪比。

This paper analyzes two common methods for improving the SNR of the test statistic: coherent integration and noncoherent integration, then points out their problems when used in low-SNR circumstance;

本文分析两种常用的改善检测统计量信噪比的方法：相干累加和非相干累加，指出它们各自存在的问题。
