Abstract :
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.
