时域滤波 meaning in English
time-domain filtering
Examples
- The time - domain filter can then be used to select the narrow central portion of the cross correlation function ( ccf ) , capturing virtually all of the signal but rejecting most of the noise
对相关函数进行时域滤波,挑选出互相关函数中窄信号自相关函数部分,去掉剩余的大部分噪声能量,得到加窗互相关函数( ccf ) 。 - Taking the fourier transform of this windowed ccf produces the time - domain filtered cross spectral density ( tdfcsd ) . the snr can be improved with using the character of noise which distribute uniformly in frequency domain
再进行傅立叶变换产生时域滤波互相关谱密度( tdfcsd ) ,利用噪声在频域中均匀分布的特性使snr得到改善。 - A temporal - spatial filter is designed for noise removing of clinical eeg signals , the first filtering is temporal filtering using band - pass filter , and the second filtering is spatial filtering with ica - based spatial filter
为了有效去除临床脑电信号的噪声和干扰,设计了一种时空滤波器,分两个阶段对脑电信号进行滤波预处理:第一个阶段是时域滤波,用传统的带通滤波器实现;第二个阶段是空域滤波,用基于独立分量分析( ica )的空域滤波器实现。 - This thesis makes a fairly in - depth study on the basic techniques about the current svc algorithms by reading a lot of relevant references , including the svc system schemes and the techniques of various scalabilities . based on these knowledge , motion compensated temporal filtering ( mctf ) which is an effective method to eliminate temporal redundancy is researched , and mctf based on db2 wavelet is presented by studying the method of mctf using haar wavelet . the simulation proves that the low - pass frame is better than the haar one , it means that the temporal scalability is improved
