无限脉冲响应 meaning in English

iir ( infinite impulse response )

Because multi - band wavelet can describe signal more delicately and more compactly than two - band wavelet , and multi - band wavelet can be derived from the infinite iteration of multi - channel filter banks . by means of a detailed discussion for a effective design method of linear phase pr iir filter banks , the author obtain that the method is only fit for two - channel filter banks , but ca n ' t be extended to arbitrary m - channel ( m > 2 ) filter banks
由于m带小波比2带小波分析信号更细致、更紧凑，而m带小波可由迭代的m通道滤波器组获得，所以本章分析了一种两通道线性相位完全重构无限脉冲响应滤波器组的有效设计方法，希望可推广用于m ( m 2 )通道。
