The ratio of signal to noise (S/N) is greatly improved through the phase sensitivity detection.
通过相位灵敏度检测，大大提高了信噪比。

The bird avoided detection for so long for two reasons: Few villagers had ventured into what they consider sacred mountains, and the species—unusual among honeyeaters—doesn't make much noise.
This neural network pattern recognition can be applied to feature extraction, clustering analysis, edge detection, signal enhancement and noise suppression, data compression, such as various links.
