针对群智能机器人系统的特点，提出了一种基于单一频率信号的声音协作定向方法。
A collaborative direction estimation method based on single frequency sound is proposed for swarm-based robotic systems.
该方法综合了现有方案的长处，可避免单一参数(频率差、相角差或电压差)不满足就闭锁快切的弊端。
It integrates advantages of present schemes and avoids the unreasonable blocking for single unqualified parameter, such as the frequency difference, the phase difference or the voltage difference.
常规放电状态检测方法由于仅采用单一的特征量进行状态判别，因此在加工信号频率高、加工波形产生畸变的微细电火花加工中，不再适用。
Conventional discharge condition detection methods extracting only certain eigenvalue are not suitable for the Micro-EDM due to the high frequency and distortion of voltage wave shape.
将三种单一离散频率叠加起来可以形成一个更加不规律的组合，傅立叶变换提供了一种将信号分解成各自频率成分的方法。
Summing together only three discrete frequencies can produce a much more erratic composite. The Fourier transform provides a way to decompose signals into their constituent frequencies.
