Inversion of linear periodically time-varying digital filters
Kazys Kazlauskas · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 1994
This paper discusses the inversion of linear periodically time-varying (LPTV) digital filters using the idea of converting the LPTV filter to the block time-invariant filter. Explicit expressions are given to determine the inversion of LPTV filters. Controllability and observability of the inversion of LPTV filters are discussed.>
