“Aliasing cancelation in block filters and periodically time varying systems: a time-domain approach”,
IEEE International Symposium on Circuits and Systems (ISCAS'97), pp. 2421-2424, Hong Kong, Jun. 1997.
Abstract preview: A block filter, in general, is a linear, periodic and time-varying (LPTV) system. Under certain conditions satisfied by the transfer function matrix of the filter, the system has an alias free operat ... more
