frequency scale

This results on a typical logarithmic frequency scale in a constant speed.

这样的结果对一个典型的对数频率范围在不断加快。

To improve beamforming under low signal-to-noise ratio, a method based on stochastic resonance ( SR) in a bistable model is investigated by using a frequency scale transformation method.

为了改善低信噪比下波束形成的性能，从双稳态随机共振模型出发，提出了利用频率尺度变换，将随机共振和波束形成结合起来的算法。
