Invertibility of linear periodically time-varying filters

The invertibility of linear periodically time-varying (LPTV) filters is addressed. A necessary and sufficient condition under which a LPTV filter can be inverted is shown using a LPTV postfilter. Such techniques find application, for example, in aliasing cancellation in multirate systems
