Contrasting to the Fourier filter, the single lobe filter has not side lobe, and its data window length is not restricted to multiples of one cycle. 对传统的傅立叶滤波器与一种新型的单瓣滤波器进行了比较研究。
The mean filtering, whose window length can also be modified adaptively and pattern is selective, is used to remove the noises step by step. 采用窗口长度自适应调整和选择性取样的均值滤波方法,对检测到的噪声点进行逐点滤除。
For the purpose of improving the real-time capabilities and the efficiency of the recognition, a method of dynamic window length short-time energy is used for endpoint detection for speech signals. 为了提高语音识别的实时性和识别率,采用动态窗长(WINL)短时能量进行语音信号的端点检测方法。
Of course, Q accuracy is also related to seismic data quality and window length. 当然,Q值计算精度和资料品质、时窗长(WINL)度都有关系。
Otherwise a short window length is obtained. 反之最终数据窗长(WINL)取得小,从而实现了数据窗长(WINL)的自适应。
