摘要

本文提出了一种在频域分析和合成线性时变(LTV)数字滤波器的框架。LTV滤波器通过连续使用线性时不变(LTI)滤波器来建模。本文还讨论了时变数字滤波与短时谱和广义频率函数的关系。此外，我们还提出了一种有效的实现方法，减少了滤波系数的数量。

Time-varying digital signal processing

The present paper develops a framework for the analysis and synthesis of linear time-varying (LTV) digital filters in the frequency domain. LTV filters are modeled by the successive use of linear time-invariant (LTI) filters. The time-varying digital filtering is also discussed in relation to the notion of the short-time spectrum and the generalized frequency function. In addition, we present an efficient implementation procedure which reduces the number of filter coefficients.
